What kind of velocities are you getting out of your 30carbine AM iii?
Do most of you shoot factory ammunition or do you reload?

I’m using 110gr FMJ’s with vihta N110 and I’m getting really tight groups. 
The velocity is just 435m/s or about 1430fps which seems quite slow to me but it feeds and ejects fine. 

What do you guys use?

I’ve worked up Hornady 110 grain round nose, bullets, as well as Missouri bullet company, 115 grain Hi-Tek bullets.

This is the max load for the Hornady 110 grain round nose bullet:
W296 15 gr, COL 1.670, REM 7 1/2 primer:
-MV 1615 fps, SD 6
-1” group at 30 yd
-brass flew 40 ft and I broke an ejector

While I liked the performance, this load was clearly not going to keep my Automag III healthy for long. I worked up a more low-key load with the Missouri bullet company:

MBC 115 gr Hi-Tek RN, COL 1.68, Fed #100 primer, W296 11-13 gr. The best results were with 12 gr:
-MV 1392, SD 9
-1-2” group at 30 yd

The 115 MBC load is a pleasure to shoot, drops the brass just behind my right shoulder, and doesn’t beat up the gun. It will be my standard range load.
