i am loading on a lee single stage press using lee dies. i have used this same setup in the past but its been put away for 6 months or so. i dialed everything in the same as i always do. full length sized some once fired brass, headstamp is F C 308 Win. i trimmed it with a possum hollow manual trimmer, deburred inside and outside the case neck, seated the primer, added 42.0gr of RL-15 and seated a 168gr Hornady HPBT. same exact load ive shot a few hundred of out of my SPS-V build. got 10 rounds loaded tonight, came in to test fit and its very difficult to chamber the round. it will fit in the mag and drops into the chamber but when closing the bolt, it needs quite a bit of effort to get the bolt to cam down. my new rifle is a R700 5R milspec. maybe the chamber is a bit different and i dont know the difference? i am wanting to double check this before i start cramming rounds into a chamber and have pressure issues with a new gun. the gun is clean and will lock the bolt in place easily with no round so it has to be an ammo problem. am i overlooking something?
