ive put about 2000 55gr FMJs of wolf through my AR, about 5000 FMJs and HPs through my SKS. i dont know if WOLF still makes 12ga. buckshot, but ive shot about 50 rounds of 00 with no problems.
I have shot many rounds thru 1911s an other 45s ,AKs ,SKSs ,AR15 .....no problems ........honestly ...its as accurate as any lower priced brass stuff !!.. its cheaper an no need too worry about the casings unless Im at an indoor range an then I police all shells!!!
Its all I feed my SKS, has been accurate and never caused a problem in mine.
Have about 900 rounds of it in 9mm cradled in an unopened spam can, just been sitting on it since '07 when I picked it up. Haven't needed to dig in to it yet.
I've shot "lots" of Wolf, Tula and Monarch steel-cased ammo in my Mini-14 and SKS. Never any problems, just dirtier than the Remington UMC I also shoot.
