New to Neck-Only Sizing ... How to Handle New Cases?

[ronsatspokane]

Hmmm...given that I seem to disagree with at least half of what that fella suggests, from toilet bowl cleaner to "don't ever seat in the lands" ... I'm not sure that one could ask for a more ringing endorsement. Thanks!

(Just saw his video "STOP NECK SIZING YOUR BRASS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" ... what's up with all the shouting, and why would he possibly care "what everybody else is doing"? Kinda reminds me of the charter captain I used to fish with who would get on the radio with bogus loran numbers to try to send other anglers -- or at least strangers who didn't know him and his tricks -- away from the bite. Less competition = more fish.)

I have done it in the past. When I first got into F Class. My scores sucked back and I had no idea why but as time went on I refined my load development technique, my shooting technique and my equipment and my scores improved. Still not at the level of some of the top shooters on this forum but there are days when I can hold my own.

Fast forward to earlier this year and I got lazy. Had 300 rounds to prep and I decided that I did not need to full length size. The cases had been fire formed the previous firing so I just neck sized them. They shot like a shotgun. Was the neck sizing a coincidence or a causative factor? I say let each person find out for themselves.

Keep in mind that when I say like a shotgun, there are many who would have been happy with the results. More than minute of deer.

I see a lot of comments about this; I believe the OP was asking about new brass. JMO but from the first firing if all is well with case prep to start and you're shooting a bolt or single shot rifle? I would fire the case at least 3x before I did any sizing other than a neck sizing, so the cases get fully fire formed, if your firing an auto loader then a full body sizing is usually required, the reason I suggest this method is your brass will be more consistent when you set your body sizing die up for your shoulder bump which then I would size the brass every time YMMV.

For new brass, I just neck size with the Lee Collet die. Fired brass gets run through a Redding body die to size the case and bump the shoulder, then neck size with the Lee Collet die.

Just last night I pulled apart a doz rds of load testing ammo, I set the FL rcbs sizing die to only size the neck(die gutted). Then ran a dry lubed mandrel thru the necks to set the interference fit. Loaded back up to the load I found last fall. Ready for a Wyoming elk hunt.

With my brass and calibers I also FL neck size my brass. I measure every aspect of the brass before and after, and only the neck dimensions change. Never pushed the shoulder back at all. . But that is my chamber, brass and dies. You never know so I FL all of them. I don't even have to lube the brass, just inside and out side the neck. You will find out what is best with your set up. I"m not a fan of neck sizing only, better to run a mandrel after you neck size for less neck tension with my dies. I don't know if you need to FL all your brass, but it's the same amount of effort for me, because the die only touches the neck if all is well. And if not, you will know. I guess I'm just very safe, I have been around guns that have exploded from bad reloading practices. So I'm paranoid and need to think all the time now about each step.

Gotta love 222 and H322 ... I thought I was done buying guns! Y'all are a bunch of enablers.
