I just recieved an 1894 357mag carbine on a trade. It has the micro groove rifleing and i was wondering what is the best load to use with this rifle. I usually shoot copper coated lead in the 158grn range. Will jacketed loads shoot better. Should i fire lap to smooth rifleing or is it necessary?. I know lots of questions but they are such a great little gun i want to give it a chance to live up to it's potential.---Thanks much guys for the help.
