I have thought about 458 or 375 from an SBR, but neither would work with existing cans I own now.
My go to for subsonic is 220 gr 300BO. But yea, a 600gr chunk of lead would be ass-kicking. |

A subsonic 600gr 458 Cal bullet would work really well in an SBR.

I've heard some good things about that round, but have no experience with it.

It actually is. Loses little velocity going from a 16 inch barrel to a 10.5 inch barrel. I would like to try some 200 grain polycase out with that… I really like the polycase ammo. I've been considering a SBR, if I can make one make sense to me… the .458 SOCOM is my number one candidate at this point in time.
I think it will ROCK...

.375 H&H
45-70 well its the thought that counts in an AR pistol length I like the 300 Blk but I've come to terms with the idea that sometimes its more important to have one ass stomping big heavy bullet than a whole herd of little ones.

As I said, anecdotal. Your anecdotes do not align with my anecdotes. A shorter barrel means bigger fireball too. My ARs, suppressed and unsuppressed, are appreciably louder as the barrels get shorter, same ammo, same can, same shooter observing. Do you, Lockjaw, have any permanent hearing damage?

Mine is an 11.5 in 5.56, and to be honest, I can't tell much diff between it and a 16in one as far as noise. Both of them have the regular mil spec flash hider on them.
Even when I shot it inside to get the red dot sighted in, I was expecting it to be way louder based upon what everyone here has said, and I didn't notice it either. With muffs on. I was shooting regular 55gr ammo.

I am running the M4-2000 on the SBR. If I went up to a bigger caliber, I would probably run my Specwar 762 on it. I guess I have shot it in a few different venues. Ranges, PD hunting, fields and woods. All seems loud when shooting. Standing 3 feet back when someone else shot wasn't bad at all.

Short barreled rifle. Anything under a 16" barrel you have to pay a $200 tax and get permission from the ATF.

Indeed. The short barrels are crazy loud.

...And it will be appreciably louder from an 8" than it was from a 16".

I have a 16" and 8". Mine lost around 200 fps with super sonic loads to the shorter barrel. You will likely be around 2100 to 2200 with 110s and your 8" barrel.

What can are you using? Are you shooting indoors or heavy woods/other structures? At its core, short barrel is loud barrel. I run a 10.5" SBR quite often and it is comfortable outside and in open spaces, but yea, gets uncomfortable in environments where sound can bounce around. If you are using a 30-cal can on a 223, I have found them to be louder, even though they have higher volume. This is anecdotal, no metered data to substantiate it.

Thanks..... I'm going to look at using my blackout I already have with supersonic ammo and do some testing.... its an 8" barrel now but thinking slightly more would be better here but if I can make 8" work I will. |
