The 6.5X47 Lapua is an equal opportunity powder burner. During the current component emergency I have used: Power Pro 4000MR (140's), H Benchmark (120 & 123's), IMR 8208 (120 & 123's), StaBall (120 to 140's), H414 (120-140's), Alliant R16 (140's), CFE223 (120 & 123's), VV N140 (120-123's) & H4350 (140's).
I use whatever powder is left over from .20P, .204R & .223 with 120's & 123's for shooting rodents meaning IMR 8208 & H Benchmark, & CFE223 - real good velocities. With H4350 & RL16 the tiny little round rivals the much bigger 6.5-06 with 140's. I like the low price 140 Barnes Match Burners with Rem 7 1/2 primers - jiggles steel way out there. Don't think Barnes sells blems. Pressures are probably in the mid 60 K range.
