I have an 1895CB, an 1895G, and a BC. The 1895CB gets shot more than the others, unless I feel lazy and don't want to chase brass. Then it's the BC that's shot.
Also, I go through a LOT less ammo when shooting the BC.
Accuracy?? Probably little difference, but the 1895CB is more accurate for me mostly because I have a tang ladder sight on it. It has nothing to do with the gun's capability, just my old eyes.
As far as strength, Tim answered that. But for me, it makes no difference cause I'm not gonna shoot any loads that test the metal's temper anyway.
