Good afternoon folks, so I just loaded up 50 rounds of .308 in new Lapua brass, I did ream the necks but other than that no prep. I did seat a bullet in one (empty) and it chambered fine, I also chambered all 50 brass without bullets just to see if I needed to resize or not. Fast forward through priming powder and pills I found that some bullets seated normally and some went in too easy. Since then, I read the post about full prepping even brand new brass wish I had read that first so anyways my question those ones that seated too easily does that mean that neck tension is not enough and I’m gonna have issues with pressure? Should I pull them and dump them all and resize the brass and oh yes I checked case length they were all under SAAMI specs for length. I will be using a chronograph so should I try them out anyways and just see if I’m getting pressured differences or yeah just pull them all and if so, can you full length re-size with the primers in so I guess that’s actually three questions. Happy to provide more details.

I don't have a crimper, can they be sized with primers seated?

You have a crimp built into your seating die
Just read the instructions for your dies

There’s two types of crimp.
It’s recommended that your brass be all the same length but for a very small crimp a little variation won’t matter
 
Since it’s the first ladder of this bullet/powder combo I think I’ll go with the extra work and full length size just to ensure I’m gonna get good data versus wondering. Thanks for all the replies guys again.

just take them to the range chamber one at a time and fire form your brass there will be no issues with pressure or anything else
always re size nes brass
 
I have loaded hundreds of new Lapua brass with absolutely no case prep, and have never had a problem. In fact while getting ready for the World F-class shoot in 2013, Varget became unavailable, and with little time to spare all my match ammo was loaded with un prepped brass. Testing later showed little difference in accuracy out to 1000 yards. One consideration with regards to crimping would be your intended use. The rounds I had were loaded one at a time only. Crimping would definitely be a good idea if you were planning to shoot your ammo from the magazine, to maintain a consistent OAL.

Ok thanks, while testing I leave magazine in and single load as it adds to barrel cooling time , this one is a pencil barrel and developing a hunting load and shoot 2, cool to ambient temp, repeat.
