Here's another plug for the .280Ackley Improved. Its Steve "dogzapper" Timm's magic load.

61.0 grains of H4350 and the Nosler 120 grain Ballistic Tip.

In my rifle (23 inch #3 Shilen chambered and fitted by Mickey Coleman) this load produced an average velocity of 3,323 fps and all groups thus far average around .350 at 100 yards with none larger than .500 and between 1.0 and 1.25 inches at 300 yards.

Here's a great load I struck on for the .350 Remington Magnum.

57.5 grains of VV N 140 and the 200 grain Hornady Spirepoint. Velocity from the 22 inch barrel of my Remington 673 averaged 2,566 fps and all groups hovered around 1 inch.

This is a mild to moderate load where the velocity could no doubt be substantially incresed. However, it is so accurate and the recoil is so mild (.308 level) I never saw the need for more powder. It should be a great close cover load for whtetails, etc.

I agree with those who suggest limiting to the original few cartridges JB nominated. If everyone posts every great load he's ever found, it will quickly become useless.

To carry out the original purpose, I'd suggest a separate thread for each cartridge/bullet/powder combination, as a "sticky" at the top of the forum.

I would second that. Otherwise we'll end up with the whole Reloading Forum in one thread.

I totally concur and was only joking about the rounds I mentioned.

This could be a cool thing that JB has started if it stays on track, which should be a heck of a challenge for the people around the "Fire"...grins

Here you go MD, I am sticking with your original list.
.223 Rem 700 ADL rechambered from .222,24" sporter weight, 6.5x20 Leupold set on 10x.
26.0 TAC, WW case CCI BR primer 50 TNT-- 3129 FPS 1.5" avg. groups. Sorry 5 shot not 3 shot groups.

.257 Rob. Custom Mauser 22' barrel 3x9 Leupold on 9x.
46.0 H4350 Win +p case CCI200 primer 100 Nos. B.T. 3102 FPS 1.25" avg of 3, 3shot.

.257 Rob. Ruger #1B 26" barrel, 3.5X10 Leupold on 10X.
46.0 H4350 Rem. Case CCI 200 100 Nos B.T. 3232 FPS 1.5" Avg.
Same load with 100 Sierra Flat Base 3106 FPS .875" Avg.
Same load with 100 Hornady Flat Base 3147 FPS 1.188" Avg.

.257 Rob. Ruger M77 22' barrel 3x9 Redfield on 9x
46.0 H4350 Win +p case CCI 200 100 Nos. B.T. 2856 FPS Big Groups 2" plus. Very long throat in rifle causes low vel. and poor accuracy.
All velocity is instrumental at 12 ft. not corrected to muzzle.
I do not shoot any of the other calibers listed.
Also note that this is my 3rd different lot of Tac and all seem to burn slower than yours. I did increase the powder charge
and received better vel. and accuracy. Still working with it as accuracy so far is not as fine as with H335.

More on the .257 Roberts and H4350: Ruger M77Mk2 22" barrel, Leupold VX2 2x7x33

Win +P case, WLR primer, 46.0 H4350, Hornady 100 grain spirepoint interlock, 2.877" COAL for a .010" off the lands length.- 3050 fps average velocity 12 ft from muzzle measured via Chrony Beta master. 1.0" average for 5 shots.

46.5 grains gives 3120 average for 3 and the same accuracy from the above gun with all else the same. No pressure signs at all, very round primer, no more case head expansion than factory +P loadings which is virually nothing. I stopped here because it is everything I wanted from a .257 Roberts, I have a .25-06 if I need more speed or a heavier bullet.

I really like this load it doesn't cut clover leaves in paper but it slams whitetails. Haven't been able to keep one inside a chest to 150 yards- as far as I've had the opportunity to shoot deer with this load. The last deer was a nice fat corn fed doe at the 150 yards.

The other .257 Roberts load that really sings is 46.0 of H414 and the 100 TSX runs 3140 and 3/4 inch from this gun.

Nominating:
1) 300 WSM, 180 Accubond, 68.0 H4831SC, Fed 215M
2) 22-250, 50gr V-Max, 35.0 TAC, CCI 200

JB,
The H4350 30-06 load is what my son shoots.
168 gr TSX, fed 210m primer, It's had days that have averaged .50-.75, but overall it averages just under an inch.
It's a Sako 75 with a 22 7/16's barrel, chronograph average of 10 shots 2754.

Only one I can help with.

Model 70 classic stainless .270win 24in barrel

130gr Sierra Pro Hunter

John, Is that the same Mod 24 that "kicks"?

Dennis

Dennis,

Yeah, it is.

Dennis shot this rifle (once, twice?) while resting it over the hood of my pickup during a deer hunt here in Montana a few years ago. The load was Federal's High Energy with 180 Trophy Bonded, which averages around 1.4" for 3 shots at 100 yards, and chronos just under 2950 fps--sort of a .300 Win. factory load, but in a 6.5 pound rifle. It does tend to come back a little!

JB

Dober,

You should see some of the requests I get for load data on the loaddata.com site. Like, "I bought this rifle chambered for the 6.5mm/.348 Win. Rimless Improved," and your site has no data. What gives?"

JB

To everyone,

This is supposed to be a test of rather common loads in rather common calibers. If we let every favorite load in, it defeats the purpose of the thread. So sorry, no more IMR 7828 with 150's in the 7mm STW (which from what I gather is just about dead as a factory round these days) or .350 Remintgton Mag loads (breathing a little more than the 7mm STW but not much).

What we are trying to find out if there are "accuracy loads" for common chamberings.

JB

JB, does the H-4350 load need to stay at 58 grains,My standard load is 59 Grains is this acceptable?

jwp: Ditto that load; what are you getting?

Do I understand the rules to be we gotta use MD's loads listed at the beginning of this thread?

I have a 26 3/4" Krieger barreled Pre-64 and it gets 3020FPS the same load out of my Brother's Stock M-70 classic gets 2900 fps.....

I'm a hair under 2900 from a 22" p64 FW. 165 Sierra's.

John,

I am going to join in for the .30-06. I will run some 165gr. Gamekings over H4350 this week, and when I have a couple dollars available, I will do the 180gr Partition over Hunter.

Should we be seating these to a specific depth, or is that up to us?

I don't know if there would be much interest in this one, since it isn't a hunting load, but rather a straight accuracy load. It's the most accurate load I have found out of my hunting rifle, and I use it for practice, since I can be sure any bad shot is a fault of my form rather than the load. 57gr of H-4350 and 175gr Sierra Matchking.
