Here are some groups shot recently with the MRA 5R Match Stainless 308 SPR barrel.
These barrels really like the 175gr projos. The Federal SMK 175gr really tight at just over 3/4" inch. Surprisingly good results from the surplus Hirtenberger 147gr. The 165gr Gameking grouping tight enough for a majority of hunting situations. Not sure if that flyer was me, the ammo, or the barrel. It was -3c degrees and my hands were frozen. I think in better conditions these groups would tighten up a bit.
All in all, I'm happy. I hope you all feel the same.
Check out the weight on the barrels. A little less than the CAD calculations!
Ps. These are test barrels. Production stainless barrels will have our signature blasted, matte finish
* The round to the immediate right of the 5 round group was from a different group of shots so it was not included in the Range Buddy app.
