I load 158 gr .357 projectiles for my pre victory. If you have. 357 bore you can get away with reloading 357 or 358 bullets that are commonly available anywhere.
Simple way to tell if you have. 357 bore is by inserting 38 special cartridge in to the muzzle and if bullet does not sink all the way to the case edge, then you have 357 bore. If it does come close to the edge of the case, then you have. 362 bore that does require proper bullet for the cartridge.
Again it all depends on what firearm or condition the ammo is intended for.
