Love my camper, but guess I got the fussy one. My daughter had never shot before. From 10 yards she put 8 out of 10 rounds in the red on her 3rd magazine, and says "daddy, is that good?" Damn kid!
FYI: Got stovepipes with several brands of bulk ammo. Called Browning, really nice laid back guy told me I could send it to them, or first try what they do. Run CCI ammo through it. If it has no problems with CCI, they wont do anything to it. So I tried some CCI ammo and for a few cents more, absolute perfection. Or fire Federal with 1 or 2% stovepipes, or other brands with worse results. Short story long, it's a great, fun gun.
Isosceles? Weaver? I practice shooting over my shoulder while running away!
