I’m tracking on the USMC SAM-R chamber. Quite a few people claim that it has less accuracy potential than the Wylde. While that may theoretically be true, I don’t feel disadvantaged by it. Hence the comment.
The 10 ring is 1.75’’ in diameter. That is what I used to calibrate the software, resulting in the 0.543 MOA / 0.569’’ reading .
I don’t remember anyone posting any factual data about any accuracy differences between the various niche chambers. Certainly quite a few people and companies have seen room for improvement over 5.56, and its one of those things I don’t think you can really go wrong with any of them. Ive owned two guns with Wylde chambers which shot some sub MOA 10 shot groups, no reliability issues with a wide variety of ammo, and were about all you can ever ask for in a gun.
At any rate hopefully you can keep duplicating those groups and keep us updated on how it goes. Wish I had an indoor range to test stuff out with. At the range I shoot at there are usually 10-15MPH winds and its often worse than that.
Yeah I haven’t seen any empirical data either. Just the usual " X is better than Y" comments. I don’t know enough about chamber geometry and how it affects accuracy to make an informed decision outside of actually shooting the damn things.
From what I can tell, the Wylde, Noveske Match Mod 0, and SAM-R chambered platforms are all working out fine on their respective platforms.
The indoor range is great for shooting groups in absolute still air. Waiting for the target board to stop swinging back and forth after you send it down range on the cable is another story. Pain in the ass, but worth the wait.
My BCM 18 inch SS410. I expect it to group closer to .5 MOA at 100 yds, these shot groups are sloppy and it’s my fault. I’ve shot it out to 318 meters and it performed as expected, no pictures though.
