That's impressive!I keep forgetting about this, finally picture proof I can do it too.........

Tricky campbell river winds to keep everyone on their toes.....but I did it, and not just once today but I just want to post this one because I know I can do better, and will strive to get the picture proof to back it

Nice shooting! Wind sped you!
Especially the group from Tikka CTR barrel and action 6.5 Creedmoor, you are going to break 1" soon!

Awesome group! What are the specs on your barrel? I assume from the fast twist that it's aftermarket? Cheers!
Made it out to the range today, struggled a bit with my scope vs my target dot size but whatever, no excuses.
Plus 5C, wind was gusting from the north. (headwind) Was not to bad to be steady.
Savage Stealth, 6.5 Creed, Heathen Brake, 325yards (300meters) 140 VLDH, 2710fps
Harris bipod, rear bag, shooting off a concrete bench. (hate the bench lol)
EDIT: Whoops read the rules and remeasured. That is a better way to measure it, 2.168 outside to outside - .264"= 1.904"

Thanks.
3.11" group
302 yard target, 1 moa = 3.16"
3.11 " / 3.16" = 0.98moa
Maccabee Defense SLR chambered in 6.5 Grendel
19.6" 8 twist Odin barrel
Bushnell Forge 2.5-15x50
A very nice attempt with a gas gun todbartell!! I have no doubt you will get it to shoot under 3" next time. Nice AR man.
still trying for sub 1 inch, so so close today, 1.081 10 shot group with a rebarrelled savage f class rifle, Jury 12 twist 6mm barrel MTU contour in 6mmbr, 80 grain bergers over Varget and CCI 450 primers. 300 yards again, heavy left to right winds but determined to hold the impact in the center for score.
