UC,

It's possible that those cracks were caused when the welds cooled down. In which case, they would have been there when you got the rifle but you didn't notice them.

I love the consistency of blackpowder but it gets whatever it propels to velocity quickly and the recoil just seems sharper. I have a friend with a Savage ML. We were shooting the Buffalo 375 SSBs with 44 grains of 4198. I was amazed at how modest the recoil was because were were getting velocities above 1650 with it. 100 grains of 3f black powder can not do that and I can tell you, that the recoil with 100 grains of 3f Goex is pretty sharp under a 375 grain SSB. It leaves a mess around the plug like that also.

UC that breech plug in the Accura looks alot like the plug in my Kodiak Pro. Do you know if they are the same? If they are, does BH 209 work consistently in the Accura?
