Farmer, at 6.0grs of silhouette your just breaking into +p pressures if your using a 124gr projectile based on book. But man you've got 100fps more than book velocity! Is this normal with silhouette or do you think it's just your barrel?
Haywizzle, how was the WSF for muzzle flash? Also thanks for the link to that tool, I'll be be trying that out!
I did some more reading last night and stumbled across winchester 572 which looks promising as well. Folks on here either loved it or hated. But the data shows that even at max book load pressures are nicely below the 35k psi mark.
