Home Forums Reloading Varmint Rifles Your Most accurate 223 load with 50 BT?

What say you?

In a bolt gun, a near max charge of W748 or H335.

H335 and find pressure.

In a couple guns.......50BT, 26.5-27.0/VV133, IMI, Rem7-1/2BR.....14" twist. Approach carefully.

H-4895 @ max.-Muddy

26.0 grains IMR 4895

27.0 grains TAC

H335 will normally group well, but so will TAC, with just about the same charges. I've been using 26.0 TAC for a few years and haven't encountered a rifle that wouldn't shoot it well. Also discovered a couple-three years ago that one of the major bullet companies uses TAC as their standard powder for testing 50-grain bullet accuracy in the .223.

More recently, 23.0 grains of Accurate LT-32 has proven VERY accurate in more than one .223 with 50 BT's. Velocities are a little slower than with TAC and H335, but not enough to matter to a prairie dog or coyote.

Nice to see you like the LT-32 MD. Mine likes it too.
23.5 grs. LT32 w/ 50 BT's works fantastic
25.8 grs Benchmark is also.
335 ain't bad, but it's dirty
8208XBR works but only max + a pinch with mag primer for me.

AA 2015 BR 24.2 grains with a 50-55 shoots very well in every 223 I have tried. 2208 and H4895 produce similar results

H335 and i could care less about it being so called dirty , because i clean my rifles every 20 to 30 rounds , old habits are hard to break. I have been able to get Tac to group as well as H335

I have a Rock River arms Lar 15, with 25.1 gr of Benchmark and the Nosler BT varmit bullet it shoots groups that average half inch. However best group that I have shot so far was with the Sierra 52 gr HPBT match king, 25 gr Benchmark resulted in a group that measured .295, same load shot a group at 300 yards that measured 1.895.

Try some Dyna Bore Coat and keep shooting. Every 20-30 rounds and I'd give up shooting.

I run 4895 under 50 BKs and VMs, they shoot great as that seems to be the optimum burn rate (or something).
335 was the same way, but I don't shoot it any more. One too many really hard bolt lifts for no good reason.
TAC is also impressive under 50s. All loads just under official book maximums.

max or near max loads of Benchmark are my most accurate loading

not the same burn rate, so not the same charges, but also not the same issues ( like hard bolt lifts due to pressure spikes in hot weather, dirty etc), but an old Benchrest Shooters Standby,
H 322....

Certainly not the fastest at 3,150 fps, but 25.5 grains 2230, Fed. brass, and CCI standard primer has proven accurate in a Ruger bolt-action.

thank you all

a full case of varget with the 50's works well for me.

It's interesting that Ramshot TAC is recommended sometimes, but very few people seem to try Ramshot X-Terminator. In .223 and 5.56, for all weights up to mid-60 grain bullets, I've found X-Terminator to give better accuracy and slightly more velocity than TAC, 748, or H335. Both TAC and X-Terminator seem to give best accuracy with max loads.
