So. I had opened a thread a few weeks ago discussing issues I had with my 28 Nosler in A Christensen Ridgeline. Showed what appeared to be pressure issues...headspace maybe? Needless to say, we sent it back to Christensen. There’s no way that rifle was tested before being sent out the door. No matter what ammunition was fired through it, factory or hand loaded, you had to beat the bolt handle up. Anyhow, I never did find out what the issue was. So they sent me out another rifle. This time instead of the 28, I chose to go back to my favorite caliber, The 300 RUM. So now onto my next concern. Taking an empty (no bullet) full sized Norma brass and feeding it, feels ok and bolt seems to close smooth. No, loading up a 190 Accubond LR at Mag length (3.800 I believe) no way bolt handle would come close to closing. Working my way down every few thousandth, around the 3.680 the bolt would finally close but it felt very gritty and rough...like it was digging into the lands. So long story short, I’m all the way down to 3.540 and it still feels the same. That is seated ridiculously deep. I’ve loaded 6 rounds the same and all feel terrible closing the bolt. I don’t have any factory ammo to try. Can someone maybe point me in the right direction? What am I doing wrong here or what to try??
