Neck size or Full Length ?
- Thread starter Stingray
- Start date
If shooting in a bolt or single shot and able to keep brass with gun it was originally fired in, neck size only.
If shooting in a semi-auto or gun other than brass was originally fired in, full length size.

Anneal and full length but bump shoulders only 0.0015" during resize.
I'm with Mark. The only gun I neck size for is the 300 wm.
This is what I do as well, using a FL sizing die but just bump the shoulders back a couple of thousandths on the cases that will be fired from the same rifle again.
Lee collet die for my necks, when the shoulder needs to be bumped I use a body die to bump shoulder the run it thru a Lee collet die.
Yep, .002" here

Neck sizing sucks

I have always full sized my brass, don't even own neck sizing dies. I will admit that I have looked into it, but even though there were plenty of videos saying to neck size, I watched/read enough to not change to neck sizing.

I agree with Omega 100%. Neck sizing is NOT the right answer. Full length size every time.
Omaga, thanks for that video. As a rookie reloader I've wondered about neck sizing. Seeing that cast of characters Cortina polls, answers any question I had about doing it.
Non belted cartridges I full length size and bump the shoulder back 1-2 thousandths.
Belted magnums like my 7mm STW, I full length size new or once fired brass and then neck size afterwards until it gets hard to chamber and then I full length size
Belted magnums are notorious for case head separation above the belt and full length sizing weakens the case wall above the belt with all the stretch.

This is why Magnum brass is good for 5 loads and that's about it.
I do not like neck sizing. Just an opinion because I could not tell the difference in the field or at the range. YMMV

I neck size only until it gets hard to chamber.
Treat your belted magnum cases like the belt isn't there and headpsace them off the shoulder and they will last as long as anything else. .002" shoulder setback works on belted mags just like everything else. That will reduce case stretch and headspace separation. I size my 7rm and 300wm like a nonbelted case.
I use the same loads for several rifles, so I full length resize. My accuracy is still good, and no surprises when changing rifles.
I've got some factory Remington 300 WinMag brass cases that I have loaded over 7 times so far and still have at least another load or two left in them I think. I headspace off the shoulder and don't worry about the belt either.

All my sizing dies are full length dies, rcbs and hornady.
Maybe it's the Remington brass but I get about 5 loads and there is a distinct line above the belt and a notch inside the case. That is full length sizing and bumping shoulder back two thousandths.
