Neck size or full length size for AR 15?

[CRNA]

I ordered the Lee neck sizer and seater dies for my AR 15 that's on backorder. I wonder how many reloads I can get before having to full length size? Or should I full length size every time?

i would defianatly fl size every time to ensure feeding and reliability

Gas guns that are Rapid fired should be full length sized for function reliability.

I actually have to use small base dies that are fl. All my shooting friend have to do the same. Just not going to chamber without full length and even possibly small base dies.

You need to trim every time as well

Suggest you cancel the back order, unless you have a 223 bolt gun to use the neck dies with. Rule of thumb, all brass scatterers need FL dies.

I have been using the RCBS FL, X dyes for about 4 years with 3 different AR rifles. Never trimmed, no failures to feed. I was skeptical about the x dye which maintains the OAL of the case each time the case is sized. It works. I get over 10+ reloads per Lapua case. Just need to follow the instructions on the initial set up od the dye.

Cool on the x-dies; I was wondering if they were good or not.
+1 on full length sizing with trimming(rum em through a gauge for max length)
