Home Forums Hunting & Shooting Ask The Gunwriters Full Length vs Neck Sizing

Dunno if you watched the video, or whatever, but the reason you noticed an improvement in accuracy with neck-sizing was NOT due to neck-sizing only. Instead it was due to the excellent job Lee Collet Dies do of keeping case-necks aligned with the rest of the case--whether it's FL sized or not. The Lee die does this despite variations in case-neck thickness.

But the reason "standard" full-length sizing often results in larger groups is NOT due to FL sizing itself, but the side-effects of using typical inexpensive FL dies--without checking whether the case necks (or seated bullets) are properly aligned with the case body.

Should I use the Lee Collet Die to size these rounds? Why or why not?

My answer: I figure I can use the Collet Die for maybe 4-5 loads before I need to do a full-length size-- probably about the time I give them another annealing. However, this is the first time I've gone down this road.

I did fine bushing sizing Lapua brass to .336", but still not as straight as my honed out Forster FL die does it.

I don't think you will feel satisfied until you do what you want. Your answer is the correct one. Everyone else is providing what works for them or what they believe is the best. But is it the best for you? You can read all these suggestions, but in the end, it comes down to what fits your situation.

Cheers.

There are certainly as many "correct" answers as there are answerers.

I only neck size, and don't ever FL size rifle brass any more. If you use the Lee Collet die and segregate brass according to the rifle it is fired in there should be no need. Brass needing to be FL sized to "bump the shoulder back" indicates an issue with the way you are sizing - it will come out of the chamber slightly smaller than the chamber, so if it won't go back in that is usually due to something you did in the reloading process.

The reasons I prefer neck sizing are not confined to accuracy. There's less working of the brass, and less likelihood of case head separations.

I have brass which has gone through literally dozens of loading cycles without ever being FL sized. It does get regular neck annealing. Case life appears to be limited by primer pockets not staying tight (not much of a problem if you don't try to load too hot), neck cracks from not neck annealing often enough, and losing cases in the field.

If you want to find stuff out, you have to do other stuff. This video explains it nicely.

Good shootin' -Al

if you watch the video and still feel neck sizing is a better way to reload your ammo > you need to re-watch and listen to this video again. there can be a pressure problem when you just neck size your brass and why would anyone wanna get hurt or ruin his rifle by getting extreme pressure from neck sizing ?

I have owned at least a couple dozen Ruger No. 1s, made from the 1970s to very recently, and have NOT found that to be universally true. Or even generally true.....

I must have missed it, but where do the pressure problems come from when neck sizing instead of FL resizing?

I have dedicated brass for each rifle that I reload for, so the ammo, whether factory or handloaded, is never fired in a different chamber.

That's likely way over pete's pin sized head.

> maybe someday you will understand the correct way to reload ammo with full length resized brass ? with your negative comments feeling tuff behind a keyboard you won`t learn much >> but maybe try to be a little positive you might learn something ? if you want people`s respect act like a man, quit this boyish crap you look very foolish with your posts.
