Do most of you go with a full length re-sizing die when reloading for an AR?

Thank you.

Yes.

Absolutely.

Thank you.

Yes.

Especially if you have more than one....

yes, but not small base..

But a buddy has always neck sized his and never had an issue...

yes, but I "partial resize" - I measure fired cases, and adjust the sizer so the shoulder is only pushed back very slightly, no more than .002".

thats the right figure. 003 at worst.

.003" is what I shoot for.

I measure the headspace from fired brass for whatever gun I'm loading for & size the brass to .002-.003" below that number.

FL sizing, no partials on an AR.

What primers do you guys like?

CCI 41's or BR4's as 1st choice.

Rem 7 1/2's 2nd choice.

MM

CCI 450's for ball powders, 400's for stick powders.

CCI 450, CCI 41, CCI BR, Rem 7 1/2, Wolf/Tula whatever their primers are with the thick cups.

Any American primer I didn't mention has thin cups.

Why FL and not just neck size if using in the same AR?

Because AR's get dirty and need some wiggle room in the headspace area to insure reliability. With a bolt gun it's not as big of a deal because you can muscle a tight chamber. With an AR, you have to stop and manually cycle the bolt or beat in the forward assist.

I FL resize everything. Don't confuse that with sizing to SAAMI specs, I just always bump shoulders back at least ,001" to ensure reliable feeding and chambering.

If FL sizing, why not go with a small-base die while at it?

Is there a drawback to a small-base sizer?

Over works the brass. I load for 4 different AR's and a Mini 14 and have never needed a small base die. If you don't have a tight chamber it's not called for.

I have one AR barrel that did need a small base die until it wore in. Now it's fine with standard FL resized loads so now the SB die just sits in the box.

Everything that gets reloaded for my ARs goes through a small base die.

Brass is cheap.

I've never seen the need in the AR. Ever.

To say we shot some is an understatement. I still have over 100K pieces of primed ready to load brass here...

Brass is not cheap. Overworking it leads to ICS, which can stop your gun.

Why folks think in this instance if some is good, more is better I still don't know...

'Cuz we're MEN!!!

I was told to use a small base die at the gun store...

Don't believe everything you hear at the gun store. Or in Internet forums.
