I tried some 385 grain Buffalo Bullet Conicals. In fact I bought a entire case of them thinking they would shoot well out of most of my .50 caliber inlines and traditional rifles. They have to be the worst shooting conical I have ever came across. I am almost to the point of next time I cast bullets I will melt them down and make them into roundball.
I remember now. I noticed that my BB 410's did not perform as well in the accuracy dept as the 385 GPs. But I did get them to group 1 3/8 to 1 5/8" at 50 yards (open sights). What surprised me about the BB 410s was there superior velocity to the 385 GPs with 70 grain BP. Velocities averaged over 1450. Within 75 yards I like the BB 410for sheer energy but I don't feel comfortable with them beyond that range for accuracy.
Particularly, I was interested in your success (or lack of) using CVA 300 buckslayers in the White. They hated my sidekick (and did well in my hawken).
