what sort of accuracy do y'all get with your 10.5 or shorter barrels say at 100 yards? I am working on mine and want to know what I can expect.

My 10.5 sbr will hold one inch groups if I do my part shooting the 110 Barnes.

Barrel length has nothing to do with accuracy. Find a load that yours likes and you'll be fine.

If using at least a 4x scope I'd say 1 moa should be attainable and surely 2-3 moa would get the job done.

I'm wanting to do an sbr with a 5 inch Thunderbeast one day but can decide between a 223 and a 300bo. I'd really like to do a 65 Grendel but hear it doesn't do well in an sbr.

Not a pistol but 8 SBR @ 300 yards with 110 Barnes TAC-TX handloads. Scope used Leupold VX6 1-6.

Disregard high shot. Dialed in too much the first time.

I have a 9" AAC upper on one of my SBR lowers with a Geissle trigger. It will shoot good ammo at about 1moa using my thermal shooting folded hand warmers. I have not had a regular scope on it in years but I think it would be solid .75 with some ammo testing. The AAC chamber seems to shoot most rounds well.

That upper is a few years old so I am not sure if the parts are the same as what they are selling now.

I have a Sons of Liberty Gunworks 9" 300 blk SBR. I don't shoot it much and haven't tried to load for it at all. 1-1.5" groups with cheap stuff. I don't need anything more than that for what I do with it. Stupid round falls on its face in no time anyway haha

I can get close to sub-moa with an $80.00 barrel using 110gr barnes ttsx. But I'm sure thats just a lucky purchase. That being said, you won't get any more accuracy out of a 16" than you will out of a 10", all else equal.

I'm pretty frustrated with my 300BLK SBR. Ballistic Advantage Premium 8.3" shoots 3MOA at 100 yards with the Barnes 110gr. I haven't tried any other hunting rounds yet since I have so much of the Barnes left over. It's still minute-of-hog but that's about it.

2 MOA is generally considered good in 300 BLK. Which is fine, as mentioned above that's still minute-of-hog at 50 yards where it shines.

Are you talking subsonic rounds? The .300 bo super rounds will shoot point blank +/- 3" out to about 200 yards with a thirtyish yard zero. Depending on a number of factors those numbers will shift left or right but they are a good ballpark figure.
