Anyone here into firearms?

Harmonics plays a part of it too. Just never say it in the post. Sorry. Since you mentioned it. I'm going to have to check out my buddy's chrono that we used against another one just to see the difference between the two.

Out of 14 of us that have mufflers. 11 shoot high. One shoots to the left some, and the other 2, who knows.

On this rifle I got about a 2moa shift with the suppressor.

What you're talking about is "freebore", and it's typically less than the variance from shot to shot in velocity increase, and some suppressors don't have any appreciable freebore effect. At the extreme edge you're looking at about a 20fps increase or so on rifles, maybe 30-50 with a pistol.

No, the POI shift has to do with changing the barrel's harmonics, and there is no written rule.

I would challenge you to show this to me, this 150fps increase. As a datapoint, all of the rifles I've suppressed shoot low with the can, to varying degrees. Again though, it's just harmonic variance. YMMV of course. The 150fps increase though, is many times what I've seen proven.

On this topic. Found out some stuff. Some, if not all was using different loads when we was testing bullet impacts with the cans. So the results that I was looking at was crap.

Had a chance to redo this with a couple of the guys using the same loads, and my new Chrono. Impacts had very little change (1/2 MOA at the most), as did the velocity (10~25 on the avg). All of this is on 3 AR15's shooting .223/NATO, and 1 AR10 in .308. The assumption was that I thought the guys all was using the same loads for testing with/without the cans. You know when you assume something. You become the first 3 letters in that word.

On a side note, my Surefire SOCOM Mini has become my favorite can. You wouldn't think 1" and 1.5oz difference between it, and my regular SF cans would make a difference, but it feels like night and day out there on the end of the muzzle.

I have the same can for my .300 blackout SBR. It's nice for sure!

I have the 762 SOCOM RC, and a 762 SOCOM Mini. To be honest, and brutal, I am not impressed with how they perform using subsonics in my 10.3" 300BLK. I am somewhat connected to Surefire, and I LOVE their stuff, get a few free things to T&E from them from time to time, etc. so I really hesitate to say anything negative, but the 762RC and 762 Mini really are in their element with supersonic projectiles much moreso than subs. Surefire's new 300 can, though, is amazing from what I hear, on pretty much everything. However, everything sounds sexy on cell-phone YouTube vids!!!

Truth be told, I've kindof dumped the 300BLK idea. If someone gave me a fair price for my 10.3" DDM4 upper, I'd possibly sell it and just buy a 14.5" 5.56 upper to drop on there. The whole SBR thing has kindof worn off for me. The more I train, the more I realize they are just a bunch of negatives with no real positives, even working in and around vehicles.

I guess it kind of depends on what you are going to use the 300 w/can for. I've got an AR platform rifle in 6.8 SPC with a spare 300 upper. The thought was to use the 300 with subsonics and can for under 100 yards, 6.8 for 100 to about 400 yards, anything over that to switch to the AR in 308. That's just my thought process.

I think an SBR shines in the urban environment of narrow halls and doors. I think it's easier to maneuver and less likely to get banged against doors and walls. Just my

On a side note... what would you consider a fair price?

Hmmm...whatever someone convinced me to break up a factory MK18 300BLK for, lol

That said, I like a 14.5" 5.56 for pretty much everything. I can and have used a 16" gun in vehicles without a problem in the world.

Something to think about, but my 16" M4 with a full-size suppressor is still shorter than by Benelli M4 shotgun. Yeah...food for thought for all the "Gotta SBR it for indoors!" crowd.

I don't have a rifle (yet), but I do daily carry.

Got together with a buddy of mine for some range fun on my birthday/vacation a few weeks back. 100yrd/50yrd range. Beautiful day in pa. Made better by the $11 a box for 9mm deal I found at cabelas. It was one of those 1 hour only specials. I happened to be in the right place at the right time so I stocked up.

Shooting his wartime 1943 mosin. Such a sweet gun. It was dead accurate.

My table. M&P9 fullsize, shield9, a ruger lcr 38sp, and my buds new Taurus 38sp (no idea on model)

My full size 9 was shooting 8" targets and soda bottles at 50yrd. I'm pleased with the purchase. Groupings sucked but I was hitting. My friend bought that Taurus on the same day I bought the 9. It sucked so bad it's already sold. Thing was garbage. Neither of us could hit anything with it. Not even at 7yrds out.

OMG!! you have a BOOM STICK!!! My brother has one of those and a K31. Those boom sticks are crazy!! We were shooting at old rotors from a Miata at around 50yards. They blast right through them !!! That Boom stick has a mighty kick!
