I made the mistake of ordering a carbine length gas tube instead of the necessary rifle length tube.
That being said, I didn't get a chance to check functionality but checked some preliminary loads.
Tested a bunch of powder weights but here is the final loads I liked.
Barnes 85gr TSX @ 2760 FPS max hunt range 270 YDS @ 2000 FPS, 754 FT.LB.
Barnes 95gr TAC TX @ 2700 FPS max hunt range 295 YDS @ 2000 FPS, 843 FT.LB.
Sierra 110 Pro Hunt @ 2535 FPS max hunt range 248 YDS @ 2000 FPS, 976 FL. LB.
*2000 FPS is generic velocity I use, not manufacturer data
This is just a starting point. I really need to check functionality. I wasn't too concerned about accuracy today since this was my first time out with this rifle. For medium game size I like to maintain a minimal of 1.5 MOA. All shots today all under that range. Which was awesome. I can tighten groups once I spend more time with rifle. Since this will eventually be my thermal hunter all my shots will be under 150 yards.
