Archived [ARCHIVED THREAD] - 556 DMR 1/8 twist anybody else have one and what grain weight have you personally had success with?
Posted: 1/9/2019 12:56:19 AM EDT
Just picked up an "ER" series DMR to go with my other 556s

The new one is the 18" 1/8 twist  (not the really early "Jx" prefix 21"  1/10 abortion)

I know that pill weight can be rifle dependent but if anybody has one of these and has had some success it gives me a starting point.

I have a pretty good stash of Privi 75 gr match that I save for my 1/7 556s and it works great but...

I have a Faxon 18" with a 1/8 twist. It will stabilize 77gr IMI factory and 77gr Sierra SMK and TMK reloads. I tried some Nosler and Hornady 75 gr but neither grouped as well as the IMI or Sierra.

I am shooting 75 grain bullets out to 700 yards with mine.  Gun shoots Xs at 600 all day on F class targets

With the 1:8 twist, I group 1/2 MOA with 69gr Nosler BTHP @ 25.5gr of CFE223.
