Can’t chamber new Nosler brass.Posted by TorontoAlex on January 23, 2016 at 8:17 pm
Bought brand new nosler brass and ran them through the collet sizer, primed 100 cartridges. Loaded 2 rounds and just realizing now the stuff wont chamber. Should I force the bolt down or try? Any suggestions?

I tried both an empty and loaded cartridge and can force them down with some resistance. A factory Remington round will chamber easily. Should I be concerned? All dimensions are below spec.

F.l.size, then neck size subsequent reloads.

I don't have a full length sizing die :-/
It seems to chamber the round with enough force, like 5 lbs. Is this safe to shoot?

You'll need a f.l. sizing die, even if you plan to neck size for that rifle only. I don't know if it'd be safe to fire your loaded rounds or not, but I probably wouldn't shoot cartridges that required a lot of force to close the bolt. IF you're going to reload, you should also probably get a Wilson or other brand case gage, for setting up the sizing die for proper shoulder bump.

Yup, FLS or just use a bump die to bump the shoulder 2 or 3 thou back. I use Redding collet neck sizing dies and a bump die to bump the shoulder 2 thou after every firing.

If the brass is once fired in the chamber is it required to bump the shoulder back. I just got a collet die and thought the neck was the only thing required to be sized and trimmed if needed. Wouldn't bumping the shoulder back just make it form to the chamber again hence causing stress on the case that's not needed?

i have and use the lee collet sizer for precision loading. I have 3 mandrels for each caliber since press pressure is not helpful to change neck tension. all that said, you must full lenght size new brass initially to make sure it will chamber. you will also (almost certainly) need to full length sized your cases after the 3rd firing or so to bring them back into spec. new brass is variable – even lapua.

Never had to worry about this with my winchester brass. Neck sized only new unfired brass and reloaded 4 times, neck sized only, always chambered easily.
Gotta say it's a little deceiving when the (expensive) Nosler brass box says “Fully prepped, ready to load”.

Do full case prep on all new brass just so you know what you have. And keep the neck expander button in to straighten any uneven necks.
