Gas Gun Groups Thread

I didn't build my LMT to be a benchrest gun, but it's more than accurate enough for my needs. I live in a very rural area with a lot of land and some wide open spaces. I wanted a general-purpose rifle with a DMR type focus. Most of my 10-round 100 yards groups are in the .8" range, some in the .6's. It's a 16" Bartlein barrel from Craddock Precision converted to LMT by D wilson .

Currently Working on a New Rifle 6.5CM 22.375" ( Don't ask ) have sunk some coin in the latest one and so far shows REAL potential .

These targets are from one of My Aero Precision platform builds and are Very capable . Preliminary powder evaluation .

Extremely happy with MY 129 gr. Hunting load , as all #20 shots went into .404" @ 278 Yd and Virgin card board backer (y)

Diamondback DB10, 308 krieger barrel. CMC trigger. A nice rifle I’m happy with. Shoots better than I'm capable of.

15 rounds fired quickly at 100 yards. Ammo was hornady whitetail 150gr, the cheapest ammo the gun store had on hand.

6.5cm, 20" Faxon match barrel (from 2020), Aero M5E1 Receivers and Handguard, FCD small parts, TT Diamond trigger (Swapped out the Timney CE). This group was actually factory Hornady 140gr American Gunner. Shoots 140gr ELDM about the same at 100yds, but outshoots the AG at 500yds+.

338 ARC fire forming brass 338 ARC improved. Standard case longer neck, improved shorter neck.
Only improves velocity of supers a bit, subs the long bullet takes up most of the powder space.
A 50 shot group 175 gr HP, Lil Gun, Starline Grendel brass, cut and formed, 10.5 S/D 2149 fps average over 50 shots in a gas gun.
The CMMG 338 ARC specific mags worked 100%.
