I had a reemer made by pacific tool for 20 Grendel.
Had two uppers built by Bart Baldwin, Gibbz side charge receivers.
One barrel is 1:8 twist, 24"
Other barrel is 1:12 twist, 24"
Have just started load development and fire forming brass.
Shooting 55gr Bergers in the 1:8 and shooting 32 Hornady, 35 Bergers, 39 sierra's 40 gr Bergers in the 1:12.
So far no feeding issues, none!!!
So far really impressed with the groups.
The 55 Bergers are not going to be screeners, 3100fps or so.
The 32's, hahaha wow, so far just bouncing around 3600fps, but with no pressure signs and lots of case capacity left to go.
Powders so far tested, H4350 N140 with 55 gr Bergers
N135 with the 32's, going next to N530 with the 32's.
I have the reemer spec's and will post at some point when I have time.
I will post more later, just wanted to get started on this thread.
Thanks
