I have a new unfired Patriot in 308 that i just mounted the scope on. I have some issues with loading the ammunition. I was at a buddys house mounting the scope and he was explaining various types of his 308 bullets. As i go cycle the bullet it does not even chamber in fully and gets stuck. I am not able to fully close the bolt We tried all different 308 bullets and here is what fits and does not fit based on what we had . PPU Match 168g/ Did Not fit/Cycle M.A.L 7.62 (mil surplus)/ Did not Fit/Cycle Remingtion CoreLock 150g/ Fit but little tight/snug closing bolt Winchester Match 168g/ Fit Hordany Whitetail 150g/ Fit All these fit both in his and his brothers savage rifles in 308. Im going to call mossberg tomorrow and see what they think. Is it because its a unfired? is there a break in?Any input will much be appreciated.
