I would like some chronograph work or just please post some info. you already have.Ultramax offers a 165gr. .30-30 load with 1170fps. muzzle velocity, it is a lead cowboy load.What load out of a .357 in a rifle offers this same or near velocity?.38 special, .38+P? I think the .357 full house loads are about 1500-1900fps. out of a rifle.I want the 1170fps. mark with factory ammo.
