First of all, thanks for the forum!
I am in the process of trading for 600 of the bullets pictured below. Bullet hardness is unknown, but the lead cannot be scratched with a fingernail. They are sized .357, weight is 158gr, and lubed with Magma (blue). I plan on running these through a couple of Blackhawks and a 92 lever gun, with velocities under 12-1300fps (possibly around 1100). I am not looking for match grade accuracy, just a good bullet to bang steel with. Here is my question. Should I hold out for .358 diameter bullets, or will these work fine for my needs? I understand this is a rather general question, but figured you guys could start me off in the wrong direction. Thanks!
