I WAS THINKING OF A REDUCE LOAD FOR THE 270 WINCHESTER FOR A SIERRA BULLET 130 GR. WITH 26 GR OF 4350 IMR .I JUST DON'T LIKE THE 26 FROM 52 BEEN USING JUST ASKING GUN NUTS
Reducing the charges of a slow-burning powder like IMR4350 below about 90% of maximum is dangerous. You'd be a lot better off (and save money and perhaps your life) by using H4895. Maximum loads can safely be reduced 40%. Look up both the .270 data for 130-grain bullets and their guidelines for reduced loads with H4895 on Hodgdon's website.

Where did you come up with the specific charge of 26gr of IMR4350?
You could get away with 27.0gr of H4895 and work your way up from there, but I wouldn't dream of doing it with either IMR4350 or H-4350 or any less amount of H4895.
Talk to the folks at Hodgdon and ask them why drastically reduced loads are a very bad thing.
A hint- Hodgdon found that H-4895 could be reduced UP TO 60% of the maximum charge of H4895 for any given rifle cartridge. Any less than 60% could cause dangerous pressure excursions as well as parts of the rifle and your body going on their own excursions, causing you to go on an excursion to either the hospital or the Medical Examiners office for your last butt wipe.
But then, your mileage may vary 'cause God looks after certain groups of folks.

DID THEY SAY 52 X .6 = 31.2 THERE IS ALL SORTS OF INFO OUT THERE WITH 10 TO 18 GR OF POWDER FOR 1500 FT PER SEC. JUST THINK THESE LOADS DON'T ADD UP
Some internet guru wrote that you could use 10gr-18gr of IMR4350 for a reduced load or some OTHER powder?

Dude, just get some TrailBoss and don't be a grouch about it. TB is very easy to make reduced loads for and has been very accurate in every cartridge I've tried it in using cast or jacketed. The IMR website has load workup info.
I like the 4198 too. 31gr of H4198 in my daughter's 20" 7mm-08 turns up 2,550 fps with 120's. Recoil is quite low and it's a legit 200yd deer rifle. I likely will look at 4895 in a couple years as a full-power option that won't require quite as much powder as the typical Varget/RL15/BigGame/CFE223 loads.
These days I also use a lot of somewhat reduced loads in the .30-06, .308, .270, 8x57 and 6.5x55 loads used in a 100+ year old M96. Not squib loads, the '06 and .308 are at about .300 Savage levels and the .270 about like a 7mm-08. IMR4895 is the powder of choice for all of them. Others will obviously work but IMR4895 has never not given an outstandingly accurate load in any rifle so used and logistics-wise it's easier to keep one big batch of the same kind of powder on hand.
Gunnery, gunnery, gunnery. Hit the target, all else is twaddle!
I like 4895 for these modest reduction loads too since it goes through a powder measure easier and does produce very good accuracy. But I got a super deal on an 8 pounder of 3031 so I'm doing like the match shooting Marines used to do and burning 39 grains under a 168.
I use a lot of a "semi-reduced" load in 308 Winchester, basically an old target load with 3031 under a 165/168 at 2550 fps +/-.
Some of my old target notes see that load locking up TIGHT little knots at 200 yards, with aplomb.

Hodgdon Powder Company has found that H4895 can be loaded to reduced levels. H4895 was chosen because it is the slowest burning propellant that ignites uniformly in reduced charges. To create reduced loads, the 60% formula is recommended. Find the H4895 load in the Reloading Data Center for your caliber and bullet. Take the maximum H4895 charge listed and multiply by 60% (.6). The load may be adjusted up from there to achieve the desired velocity and accuracy. This works only where H4895 is listed. DO NOT use in a cartridge where H4895 is not shown.

Seafire, where you refer to a load of 30 grains of 4198 is this with cast bullets or with c & c bullets?
I am interested because I want to develop a load for the 170 grain 30/30 bullet in the 30-06. Hornady data says these bullets can be driven up to 2500 fps. Where I hunt I use an elevated shooting house set about 60 to 70 yards from a bait station. I figure one of these bullets driven a little above 30/30 speeds should be a good killer without destroying a lot of meat.
At one time I developed a load with R15 powder but now the powder is gone as well as the loads I had made up. I haven't seen any R15 in at least 2 years or more.
Am also curious if I4895 powder can be used in reduced loads similar to H4895.
