Took delivery of a used Howa 270 today, and bought a truckload of cheap Prvi Partizan to feed it, but it won't fully chamber! The bolt won't turn more than a few degrees, and when removed after a fair effort, the cartridge rim looks like this.
Is it (ammo, or rifle) just stupidly out of spec?
Unfortunately I've no other makes to compare it with. I'll try and find some tomorrow but this is an inauspicious start to my 270-ing
