Has anyone on the board used a suppressor on a MLer? I realize that in 99.9% of our usage, that this would be highly impractical; but, I have a situation where all the suppression practical would be beneficial. FWIW, CF is not an option.
I’m wondering how much it would help with a regular velocity load (2,700-2,900 for me) out of a 40 or 45 and a JD Jones type of load with a 325-350g bullet @1,050 .
Thoughts?

I would guess you would have to use a saboted bullet to get the velocity sub sonic given the criteria for pressure to obturate a non-saboted bullet? Sounds like you hunting in someone's back yard???

Mine.🙂
The sabot seems very logical. I was thinking maybe even one of Cecil Epps’ all lead “incredible😊” BC’d bullets for easy obturation either 40/sabot or smooth sized.
Obturation. I will likely use QL to find a powder that will still get enough pressure to obturate well (35,000+ psi) , yet stay subsonic, if I go the subsonic route. Maybe a powder such as VV105, possibly 4756 or 5744. Just have to run the calculations. Plus the amount of propellant gas produced would be a lot less, and should help reduce noise even further. Though a much shorter barrel would produce greater efficiency, the longer barrel (26”) and the resultant slowing of the bullet within the barrel could allow for slightly high initial combustion pressure and even lower ESs. This is certainly true (lower ESs) when shooting tgt quality subsonic 22 bullets through my 26” barrel of my CZ 22 vs an 18 or 20” 22 rifle barrel.

That could go bad for the suppressor, gun and maybe the user too. Suppressors work pretty good on our guns. Tames them down quite a bit but as with using them on other guns with super sonic loads, there’s still a bit of a report. Suppressor yes but silencers they are not. Significant reduction, but not quiet.

I have seen on you tube being used, on a 45 cal

Nick uses them. His shoot is this weekend so it might be a bit to get a response from him. I don’t think he has tried anything subsonic.

Sew i would think full form with a light .015" jacket would be "the plan" for your needs or maybe smooth sized too with a pure lead core for sub-sonic . Try Northern Precision Bullets and talk to Bill the owner . Great bullets by the way and inexpensive too for far more than youre considering here as well . He will make them "your way" . Check your messages as 1 will be there .

Not that I am a fan of Powerbelts but one of their skirted bullets should easily pass through a suppressor at subsonic speed. I havent tried a suppressor on my SML yet, but I have on a 45/70 and it works wonders for full power loads and makes subsonic loads sound like a pellet gun. Mark.

Sabots would be a no go in the suppressor but as someone else stated a skirt might be ok. I shoot my .338 Federal suppressed but with full power loads at 2850fps from a 16" barrel. It acts like a muzzle brake and reduces decibels roughly 30 points. Your still going to hear it just as far as without the supressor but it doesn't ring your ears. Its technically just below hearing safe levels for the short burst of time its making sound. I haven't shot subsonic out of it as any heavy .338 pills are for the win mag and Lapua which would be useless at subsonic speeds for me.
