    These are the cases in order of which I fired them(I know there is two number twos for the case mouth).

    that got weirder in hurry.
    if your bullet got stuck in the rifling it almost sounds like there isnt enough throat.
    that would for sure cause high pressure.
    if you chamber a round and extract it is there marks on the bullet from the lands?
    there should be a jump to the lands.
    you can use a marker and coat the bullet if it isnt easy to tell by eye.

    that cratering is quite severe too. i don't even know what to think. are those bullets .220 in diameter? to be honest that ogive doesn't look like typical 5.45 ogive, more like 5.56 NATO bullet.
    measure a bullet. if stuff gets stuck AND generates over-pressure in the chamber that could be .224 bullet.

    I made an interesting finding the Tula bullet is .222 in diameter and the bullet on a Hornady Black 5.45x39 is .220 I think I found my culprit.

    I think so, I'm going to have to go through my whole lot now (about 6k rounds) and weed out all the oversized bullets.

    well, i'm glad that nothing is wrong with the rifle and junky ammo is to blame. i never trusted tulamo to be honest, although i did buy some when ammo availability was less than stellar. i think i still have 3-4k of 9mm and maybe a 1k of .223 that i'm saving for rainy day. probably should double-check that stuff and shoot it, then buy some wolf or tiger
