As stated check and trim if necessary. But you want to set your sizing die up correctly. Take a few pieces of fired brass and check them with the correct datum bushing of a headspace comparator. Say the average is 1.500. You need to set the your sizing die up to only bump the shoulder back to 1.4985 to 1.498. So only bump the shoulder 1.5 to 2 thou back from fired. It will allow good chambering and work the brass less and give more consistent accuracy. Book spec may not be exactly what your chamber is so go off your fired brass. Factory ammo/new brass is usually about 7 to 12 thou bumped back so it feeds in every chamber. But it doesnt give the best performance. Buy the Hornady bullet and headspace comparators. Next start annealing your brass. I use a Annealezz. You will get more consistent neck tension and your brass will last much longer. Then start neck turning and primer pocket uniforming and your there. Just kidding I dont even turn necks yet, probably will, or uniform primer pockets. And I get sub half moa from a few rifles. But I may need to start to get to that .25 moa levelNewbie alert...I am new to reloading and have full length resized some 7mm STW, 6.5 Creedmoor and .308. I deprimed as well on the press.
I thought I would chamber a few empty cases and see how they cycle. I noticed the bolt was more difficult to close on the newly resized brass. Is this normal? No bullet in the case, no primer but I did deburr the outside and inside of case after resizing.
