First of all dont force them or shoot them. I have found that I need to keep brass separate from one gun to the other even if same caliber. Something might be wrong if you do not full size everytime. Just my 2 cents. Good shooting, shoot straight shoot often.
bobber: First off, you did not mention: new or using brass that was fired in a different chamber? If it's pre-fired brass, the case head may be blown-out to a larger diameter, it only takes .002" or so), and the larger case head diameter is the problem. If the bolt closes on a new,unfired case, you have a brass problem. Gunsmiths over the years have always told me, " New rifle/chamber/ new brass required". 2 other areas of concern are headspace length, check that w/ the Hornady-type gauge), and last, verify over-all case length, max. 1.760". Back to the case head diameter: if the case head is oversize, the standard FL sizing die will not reduce it: you may have to use a small-base die if you insist on using the "old" brass. Your problem is most likely oversize brass, in one, two, or all three of those areas.
If you will buy a Redding 223 body die, you can resize the rounds you have loaded without having to pull the bullets.
BUT REMEMBER that the die can act like a chamber so proceed with care. Not unsafe, but be careful not to press downward if the press has a built in primer seater. You do not want to run the risk of having a small bit of fowling in the primer seater cup that might case a primer to go off. THIS IS THE SAME THING YOU WOULD DO WHEN PERFORMING THE BULLET SETING STEP.

bobber: Not to "beat-a-dead-horse", but if it's military brass, LC, WCC, etc.) it was most likely fired full-auto in machine guns and M-16s'. For functioning purposes, they all have radically oversize chambers, no SAAMI specs here), and the brass will be oversize. Basically good brass, heavy duty), but you must reduce it in size, to chamber in your Remington. I've always used it for "informal" and close-range, 200 yd and under), but Lapua is used for serious accuracy requirements beyond 200 yd. Good, usable brass, but requires more "prepping".
