Arrowhead muzzy powder question

[TBash]

I need some advice what other arrowhead muzzle loader owners are using for powder charges on 300NSR bullets?

I tried all the powders Luke recommended, H322(80gr), IMR_4198 (70gr), BH_209 (115br) and they all
yielded the velocity he said and were extremely accurate. Have heard Benchmark works, and 8208xbr too.
Good luck with yours.

IMR8208XBR is a great powder for 300gr bullets. Benchmark works good for 300gr bullets, but I prefer 8208 over Benchmark.

What about 325s or 350s?

I shoot the 350gr XLD with BH209 in 1K competition, and I also shoot it with H4895, which requires the hardened modules.

What kind of speeds are you looking at with BH209 and the 350?

Here's my actual for ......... 110grs WEIGHT .... of BH209 and the Arrowhead 350gr XLD's.

When we compete, we can't use more than 120grs VOLUME, which we end up averaging for weight. 350gr XLD also.

Would you shoot those bullets at game?

Shot this one this year with the 350gr XLD. Standing slightly angled towards me. The bullet went in the left side of his chest and exited just behind his right shoulder. Absolute perfection IMO. It picked him up and he went end over end, DRT.

Powder charge will be determined by bullet weight, powder type, and barrel length.

If Luke built the gun for you, take his advice on powder type and weights
