Hello all, I recently put together an AR. I am looking for suggestions on what your preferred powders are for 55 gr and 62 fmj. I currently have W748, I3031, I4895, RE15, Benchmark and I4064 on hand that would work, or should I consider something like H335/W844. I'm not really concerned about velocity, but would like to keep carbon build up to a minimum with an accurate load. I'd be using LC brass and bulk pulled bullets.

Thanks, Rick
