Lever Action 357 Magnum Ammo Bullet Set Back
I have a rossi 92 357/38 24" Octagon barrel that I use in conjunction with a mossberg 12 gauge and a 40 sig sauer pistol. I left it loaded through the holiday season with Winchester PDX1 125 grain ammunition. Upon cycling the action just to check its status as I usually do most of the bullets were considerably set back in the casing. Can anyone offer me any advice on why this is happening? In addition is there a better ammunition to leave loaded in the tubular magazine that is crimped from the factory to prevent his from happening. I also use the Hornady leverevolution ammo but it is specifically stated not to leave this ammunition in the chamber. I am currently leaving the rifle loaded with Blazer 158 grain JHP ammunition to see if the same set back issue occurs again. Thanks for any help and a pleasure to be joining the forum.
