Mike Venturino on "go to" loads

At gun shows, shooting matches or during casual conversations with other “gun folk,” I am often asked what’s the best load for a given cartridge. To that I must honestly answer, “I don’t have a clue.”

That said, I do have plenty of go-to loads. After owning several firearms of certain chamberings, when a new one pops up for that cartridge, my go-to load will instantly demonstrate that firearm’s potential. Inside go-to loads are some go-to powders, bullets and primers. These loads were not arrived at intuitively; they were settled upon after firing them at paper targets through a variety of different rifles and handguns in the 50 years I’ve been handloading.

Perhaps my first inkling regarding a go-to load was with my first-ever handloaded cartridge, the .38 Special. In my first decade as a handloader, by actual count over 50,000 .38 Specials were put together for a large variety of revolvers, many of which were .357 Magnums. During those years, never was I disappointed with a combination that included any shape of 150- to 160-grain bullets cast of moderately hard alloy – about 10 to 15 Brinell hardness number (BHN) – over 3.0 grains of Bullseye. Case type, primer brand, bullet lubricant – none of it really mattered.

All those bullets were sized .358 inch. Some particular revolvers might have benefited with smaller diameter bullets, such as for Colts with their .354-inch barrel groove diameters, a fact of which I was blissfully unaware in those days.

Like many readers, my first handloading for rifles began with .30-06 and Model 70 Winchesters. After a considerable amount of shooting, a charge of 59.0 grains of IMR-4350 with Sierra 150-grain spritzers became a go-to load. In current reloading manuals, that charge is over maximum, under maximum or at maximum – take your pick – but in the Lyman manuals I had back in the 1960s, it was a grain or two below maximum. Besides Model 70 and Model 54 Winchesters, that load has been used in Remington Model 721s and 700s, Savage 110s, Ruger M77s and likely others I’ve forgotten.

It is an accepted fact that M1 Garands should not be fed handloads with slower propellants, such as IMR-4350, for fear of bending their op-rods. After considerable shooting with powders in the medium-burning rate, the go-to load became 48 grains of Varget with 150- to 155-grain bullets. The 150s are for casual shooting, and the 155s are for competition.

Like many .44 Remington Magnum shooters of the 1960s and 1970s, my starting point was Elmer Keith’s recommended 22.0 grains of 2400 with 250-grain semiwadcutters cast in Lyman mould 429421. In machine-rest testing, 21.0 grains of 2400 proved more accurate, as did Lyman’s gas-checked 255-grain bullets from mould 429244. That combination was the go-to formula for all .44 Magnums fired thereafter.

Powders are usually the heart of go-to loads. For instance, back in the 1970s and early 1980s, I went through a varmint rifle craze. After trying most every varmint cartridge from .222 Remington to .25-06, favorites became the .222 Remington, .222 Remington Magnum and .223 Remington. Go-to loads for the latter two included 24 grains of Hodgdon’s H-322 powder and either Sierra 52-grain hollowpoint boat-tails (HPBTs) or Speer 52-grain hollowpoints (HPs). The .222 Remington fell by the wayside, but it provided an educational experience.

About the same time as discovering H-322, I bought a super-accurate Remington Model 40X-BR .222 Remington on which a Lyman LWBR 20x scope was mounted. In one project, a variety of primers were mated with Sierra 52-grain HPBT bullets and 21.0 grains of H-322. Five, five-shot groups were fired with each primer, and the best accuracy came from CCI 450 and Remington No. 71⁄2 Bench Rest primers, with the former actually shooting a tad better.

Nowadays any .223 Remington or .222 Remington Magnum that falls into my hands is first tried with 24 grains of H-322, the earlier mentioned 52-grain HP bullets and one or the other of the CCI or Remington primers mentioned.

With the derivative cartridges based on the .30-06 – namely .25-06 Remington, .270 Winchester, .280 Remington and one .338-06 owned many years back – IMR-4350 was always my go-to propellant. The same is true for the .22-250 Remington, .244/6mm Remington, .257 Roberts and 7mm Mauser. In fact, H-322 and IMR-4350 are easily my primary rifle propellants.

At this point I should stress that “go-to” does not translate into “always used.” In my military bolt action .30-06s, the charge is reduced to 55 grains of IMR-4350 – not to ease wear on the rifles but because the lesser charge gives velocities duplicating M2 Ball military ammunition.

Some powders of which I’m not overly fond are central to one of my go-to handloads. A good example is H-110. It has never worked well for me in magnum handgun cartridges but shines in the .30 Carbine. On hand are three M1s and one M2 (select-fire), and a charge of 14.5 grains under any 110-grain FMJ or JSP bullet functions perfectly with adequate groups.

Notes: In the .30-06, 155-grain competition bullets can be substituted for 150-grain Sierras. Cast bullet alloy for .30 calibers was Linotype; for .45-70, it was 1:20 (tin-to-lead) alloy. Sizing diameter for .30 calibers was .310 inch; for .45-70 it was .458 inch. SPG lube and Lyman gas checks used on both. Cast bullet loads with Accurate 5744 should be stoutly crimped. Brand of brass mentioned only when Mike thought it might affect performance.

Be Alert –Reduce initial powder charge by 10 percent and work up while watching for pressure signs.

Now to some of the “Old West” cartridges of which I’m so fond. Three favorites for handguns are the .38 WCF, .44 WCF and .45 Colt. In their original configurations, their respective black powder factory loads, according to an 1899 Winchester catalog, were 38, 40 and 38 grains with 180-, 200- and 255-grain bullets in the same order.

For many years my favorite handloads for those cartridges used 6.8 grains of W-231 or HP-38 with bullets of the same weights listed above, give or take 5.0 grains or so.

Years ago bullets were cast of wheelweight alloy blended with 50/50 solder (half tin, half lead) to give a BHN of about 12 to 15. Today the same 1:20 (tin-to-lead) alloy as is used in my BPCR Silhouette handloads actually serves with less leading than harder alloys.

In the early twenty-first century, Hodgdon introduced a fast-burning propellant that took up far more volume in black powder cartridge cases. Whereas several charges of 6.8 grains of W-231/HP-38 could inadvertently fit in those huge cases, a double charge of this new powder comes close to or actually overflows from the case. Hodgdon named it IMR Trail Boss, and it
quickly became my go-to powder for most handgun cartridges originally introduced for black powder. (A notable exception is the .38 Special, in which Bullseye is mainly used.)

In the .38 WCF, .44 WCF and .45 Colt, my Trail Boss charges are 5.5, 6.0 and 6.0 grains, respectively. When I have time to cast bullets for those three cartridges, RCBS 40-180-CM, RCBS 44-200-FN and NEI 324 bullets are preferred. All are roundnose-flatpoint (RN/FP) versions sized .401, .428 and .454 inch, respectively. When time is short, Oregon Trail 180-, 200- and 250-grain RN/FPs are substituted.

Trail Boss powder is much too fluffy for autoloader cartridges. Due to the small case capacity of the 9mm Luger and .45 Auto, for example, fast- to medium-burning propellants are appropriate. Handloads for each of these rounds also see use in two
World War II-vintage submachine guns (SMGs). As an avid cast bullet shooter, when I bought the SMGs, I figured alloy bullets would suffice. They work well in my M1 Thompson, and several thousand of Oregon Trail’s .452-inch, 225-grain, hard-cast roundnose bullets have been fired through it. Those same loads do not feed reliably in the M3 “grease gun.”

Once early on, the 9mm MP40 revealed it was gummed with greasy, unburned powder by firing continuously after the trigger was released but until its magazine was empty. The culprits were a combination of mild pressures and cast bullet lubes. Its barrel also leaded severely when using lead-alloy bullets. For these reasons, my go-to 9mm and .45 Auto handloads use full-metal-jacketed (FMJ) bullets – 115- and 230-grain designs from Zero Bullet Company. Accordingly, they are .355 inch and .451 inch in diameter. Powder charges, respectively, are 4.4 and 5.4 grains of W-231 or HP-38. A Dillon Square Deal-B progressive press is set up for each of those cartridges, and settings are never changed but are checked often.

Those FMJ handloads are also fine for my plethora of modern and vintage 9mm and .45 Auto handguns. For every rifle owned, I’ve tried to also have at least one bullet mould for it, although I don’t have a mould for the 6.5x52mm Carcano or 7.92x33mm Kurz.

I’m convinced, however, that the key to getting good accuracy across the board with just about any cast bullet rifle load is Accurate 5744 powder. Never have I experienced such accurate cast bullet handloads in rounds from .222 Remington to the .45-90 Sharps and Winchester as with this powder.

As an experiment a few years back, 20 grains of A-5744 was poured in .308 Winchester cases and RCBS 308-200-SIL and Lyman 311299 bullets were seated over it. Cast of Linotype, both weighed 195 grains, were sized to .310 inch, fitted with Lyman gas checks and lubed with SPG. I had never previously fired this bullet in any rifle.

Range testing was done with my old Model 70 Winchester Featherweight and a Remington Model 700V, in which I had never fired any cast bullet. The very first group from the Model 700V measured a mere .88 inch at 100 yards. The same Lyman bullet over 25 grains of A-5744 in several of my military .30-06 bolt actions gives 11⁄2-MOA groups at 100 yards.

Putting 27 grains of it under a 190-grain Redding/SAECO 081 bullet sized .325 inch and gas checked cuts the same size groups from several 8x57mm military rifles. Results have been the same for at least a half-dozen other vintage military cartridges.

The same is true in big bores. In .45-70s with RCBS bullet 45-405-FN, sized .458 inch and using Hornady gas checks, 24 grains gives low enough pressures for good condition 1800’s vintage rifles, such as “trapdoor” Springfields, original Sharps Model 1874s, Remington No. 1 rolling blocks and Winchester 1886 and Marlin 1881 rifles. According to Lyman’s current
Cast Bullet Handbook 4th Edition, .45-70 loads with A-5744 can be upped for higher velocities in “stronger” .45-70 rifles, but a
405-grain bullet at 1,200 to 1,300 fps has plenty enough recoil for me.

Preferred bullets for smokeless powder in all.45-70 loads is the RCBS 45-405-FN, gas-checked bullet, and Lyman’s 457125 is used for black-powder loads.

Handloaders need not concern themselves with any special antics when using A-5744, such as case fillers or wads to hold powder back near the primer. In fact, using fillers ensures the rifles’ chambers will be ringed sooner than later.

The only step I take with any cartridge with cast bullets and A-5744 propellant is to apply a solid crimp on the bullet to help ensure clean burning of the powder.

Developing match-quality handloads for BPCR Silhouette shooting is a detailed endeavor about which I’ve written previous articles and even books. However, one go-to tip I can give in the space here is about bullets and .45-70s.

When a new .45-70 single shot gets into my mitts, its first test rounds carry Lyman’s 457125 bullets cast of 1:20 alloy, sized .458 inch and lubed with SPG. That bullet, seated over whatever amount of black powder chosen, at the seating depth allowed by the rifle’s chamber and sparked by CCI BR2 primers will likely indicate if the rifle will be competitive. Or in plain language: Is it worth putting more effort into developing match loads?

There are many more go-to handloads, mostly for cartridges for esoteric rounds like the 8mm Japanese Nambu or 7.5x54mm French. Those listed in the tables are for more popular cartridges. By no means have I settled on go-to loads for each and every cartridge for which guns are currently in my vault. Hopefully in the near future there will be more to share.

I believe Clint Smith has said more or less the same thing, on a smaller scale, with regard to loads for service rifles. It’s not necessary to tailor ammunition to every single one, you just need good reliable loads that function well and let you hit what you want to hit.

That’s pretty much how the military operates it seems, and those poor schlubs who rely on factory stuff.

Good reading. Thanks for posting that.

Ditto. For my collection of U.S. milsurps I have a standard load built upon IMR-4895, 46 grains + 150 Sierra spitzers (either SP's or FMJ's), to duplicate pre-war Ball, Caliber .30 ammo. Guaranteed MOA or a wee bit more out of a decent barrel, a standard equaling half of what the Ordnance dept. designated for those rifles 80+ years ago. For loads meant to really make the rifles sing I substitute the 168 Matchking, but the en-bloc clips and stripper clips stuffed into the "rainy day" bandoliers carry the 150 grain loads.

I'll agree with Venturino re: 5744 powder with cast bullets, but I don't have to entirely switch over to it yet as I have an ungodly supply of SR-4759 which trumps any other powder for that application. My go-to load for .30-06 cast bullet shooting is a mere 18 grains + 180 gas checked bullet - a load which is my predictor for if a gun is worth further messing with. If/when my stash of 4759 dries up it'll be 5744 as a replacement.

Ignore the bullets in the picture. The group was a sight in check for a Remington 700. The load was 46 grains of IMR 4895 and a 150 grain boat tail Interlock. The same charge under a 150 grain flat base Interlock does quite well in a friend's Ruger American.

Did you call that flyer?😜

46gr of the Hodgdon version is my standard .30/06 load for 150s. Has shot well in about a half-dozen rifles. Before that, I used 46.5gr of I4350 with Sierra 165gr HPs; a real meatgrinder that one!

Nope.

I corrected the windage and went to the 300 yard line steel targets to practice my holdover. It's an easy shooting load with plenty of poop for the pig and deer shooting I'll do with that rifle.

The 165 Sierra BTHP out of an '06, even at sedate velocity (by "modern" standards), sure is a meat grinder at close woods distances. On the other hand, deer deaths are pretty sudden IME and for that reason I use them. I'm willing to suffer the loss of a couple pounds of bloodshot meat to guarantee a quick kill, for multiple reasons: A) it's only fair to the animal, B) it saves my gimpy butt from having to hike far to collect the animal, and C) less chance for a stranger to find it before me and put his tag on it.

Yup. You won’t learn much about tracking if you use those.

czech1022,

You might want to be careful about posting articles here. That article is still under copyright, and unless you get permission, it's illegal to republish any copyrighted material--and that includes the Internet. Mike might see it as good advertising for his books, but some authors might not be happy.

Even the O'Connor 7x57 article still might be under copyright to his family. I am working on an article for American Rifleman about the pre-'64 Model 70 .375 H&H, and want to use a photo of Jack O'Connor with his. So I contacted his son Brad and asked permission to use one--which he granted.

I know for certain that Ernest Hemingway's family has continued to renew the copyrights on his writing. Generally it's fine to use shorter quotes, say 2-3 sentences long, but not too long ago I wanted to use a several-paragraph quote from him in an article, and the family wanted to be paid more than I was getting for the article.

Eric Carmen ran into a bit of trouble with the Rachmaninoff estate a while back. He wasn't "all by himself" getting income from his music when they got done with him.

IMR 4350 is all I will ever consider using in my 270.

Mostly because of nostalgia...and because it works fine behind a Speer 130 grain soft point.

Dang! A promising new career nipped in the bud!

Too bad. I hear that in America, plagiarists can even hope to become President…..😛

That and H-4831. My go to load in my 270’s for decades was 55.0 grains of IMR-4350 under a 130 grain Nosler. Partition, AB, or BT. Now I’ve found that H-4831sc works even better.
