What kind of accuracy and range are you getting?

100 yards 1 1/2 16inch barrel with 125 Sierra softpoint at 2250 fps using 1680 powder. For more info go to BLK forum. Many loads and much info.

CMMG upper. 220 gr factory loads 3-4 MOA. Subsonic handloads with 220 matchkings about 1.75-2.0 MOA. Have not tried supersonic loads yet.
If it won't do better at some point I am likely to try a Wilson or Noveske barrel.

I can hit the 200 yard gong fairly easily. I have not shot for groups other than 25-50 yards as I am doing chrono tests mostly. I am having some difficulty getting the subsonics to cycle the gun but it is in development. I did use it on a coyote at 40 yards a week or two ago. It hits with authority but not a traumatic shock like a 223 at 2800 fps. It lingered a little.

I was thinking the only reason for it existence was, if you are going to use a can and want subsonic for night hunting .

I'm thinking house gun with subsonic loads, so if I do have to shoot it indoor I can at least keep my hearing. I have a Leupold prism scope on mine, plus a laser forward grip.
So far it has been very reliable, but the accuracy is not as good as I hoped.

I am just buying a pair of tactical ear muffs to use on my 5.56 in my house, cheaper than a can and a new upper. Then 40 grain VMax at 3600 FPS is guaranteed not to sail thru 16 walls and kill the neighbor 5 houses down.

I do have a 16" barrel for my AR10, but...

Just another toy, but makes the can seem useful.

I know, we are all sick or we would not be posting on this website. Yesterday someone told me that cans were legal to hunt with in GA now.

I have been shooting 300 whispers since 1999. 99.999999% same as 300 blackout. I shoot 18.5 grains of H110 and Nosler ballistic tips for regular 1/2 inch groups when I do my job. Subsonics I shoot 220 sierra matchkings and N110 powder and hunting I use 225 or 220 gr Outlaw State bullets. They shoot just as straight as supersonics.

I was thinking the only reason for it existence was, if you are going to use a can and want subsonic for night hunting . It is for people who want to shoot 30 cal in an AR15 and keep 30 round mag capacity. For frontal area, it is much more larger than a 223 than a 45 Auto is compared to a 9mm. Going from 9mm to 45 Auto is a 26.8% gain in diameter and a 60.7% gain in area. Going from 5.56mm to 300 BLK is a 37.5% gain in diameter and a 89.1% gain in area. So if frontal area matters to you, there is a greater gain going from 5.56mm to 300 BLK than going from 9mm to 45 Auto (the difference in diameter gain is 39.9%, and the difference in area gain is 46.8%). It has as much energy from a 16 inch barrel as 5.56mm does from a 24 inch.
