View Full Version : Another Suppressor question

Okay... I see and read a handful of suppressor talk about how quite every suppressor-can and soda bottle can be... and no talk of potatoes [ROFL1]
My question is: Using supersonic ammo (surplus, hand loads, 7.62x51 2800fps stuff..etc..) ... don't care much for the sub-sonic stuff. How much accuracy and effectiveness at longer ranges (500 yards and up) do you lose or gain having your rifle suppressed???

Looking for bullet drop data, type of rounds used when recorded, and anything else I left out... Comparing between shooting the rifle with and without the suppressor at the same known distances and with the same ammo. Anyone carrying any data and willing to share this would be greatly appreciated! Just want to get a general idea of other benefits of using a suppressor aside the tacticoolness of keeping it little more quite [Beer]

With a good quality can like Thunderbeast, Shark or Sure-Fire there is no accuracy loss.

A can will sometimes change your point of impact, but that just cause you are hanging a 1+ pound weight on the end of your barrel.

So there isn't a difference between shooting longer ranges passed 500 yards with a can and without one? Hhhmmm... I'ma have to get one :D

Thank you [Beer]

The bullet doesn't actually touch the can; unless you have a model that uses wipes.

.. the bullet leaves the barrel before the gases do, right?
So in theory the bullet leaves the can before the gas does.. thus suppressing.
So when a round is shot without a suppressor the bullet leaves the barrel the same time as the gases do?

I'm not good with physics... Just trying to make sense of things [Tooth] but does the gases in any way affect the trajectory of the round exiting the barrel?

Thank you guys for chiming in [Beer] Just one of'em weird things that went through my head... which I'm actually thinking about getting a can :D

The way a suppressor works is it gives the gasses a place to disperse, expand, and cool a little, and from what I understand the bullet does leave the can before the gasses. If you know anything about cars, just think of it as a muffler on your exhaust... same concept.

How about a video?

A suppressor will cut felt recoil too most of the time.

A bullet stops accelerating once it leaves the barrel. The little bit of gasses following it out probably has an infinitesimal effect.

typcially people see a .5" - 1" POI change depending on the range and of course the shooter. its easy enough to compensate for or just zero around.

I have noted no change in accuracy. POI does shift 0.25 MOA but this is the result of the extra weight expressed upon the barrel and not any influence from the suppressor to the bullet upon leaving the muzzle of the barrel. The groups remain dense, just down and to the right from zero (one click up, one click left and they're going where they are supposed to).

So I'm guessing that accuracy of the firearm is not effected just the POI. So here's another question to add to that: The length of the suppressor.. I take it these cans are designed for specific rounds and pressures. Which would perform (accuracy, quieter, etc...) better, a shorter or longer can?

Thank you guys for all the cool info... [Beer]

The length of the can should only affect the sound and internal pressures. Shouldn't affect the range you are able to shoot at.

I was thinking the same... adding that the longer can will also add more weight... hhhmmm... You think the longer can will also reduce the recoil?
Irving

Well it could. If longer means more weight and more gas diversion, I'd say that it would. Can't say how much though.

There is no noticeable reduction in recoil. My rifle can is a YHM Phantom that I use with QD's on 7.62 and 5.56. It's steel and it's heavy. I have another YHM (Cobra .45), which is aluminum, quite light.

With my TBAC 30P on both my 308 and 260 there is a large decrease in recoil . It also changes the recoil impulse by making it longer and softer . The other suppressed stuff that I have shot , 22lr to 338 Lapua mag has reduced recoil . In my experience a suppressor works almost as good as a good muzzle brake and the main difference being with a brake you still get the quick sharp recoil impulse .

It would depend on the can. As gcrookston said, the aluminum (and other lightweight materials) ones are surprisingly light.

Then there's always the A.R.I.E.S. Suppressor, if you want a massive lightweight suppressor (carbon fiber, your barrel length + a few inches).

Prior to that video, I wasn't entirely sure how to thread a can onto a barrel. All confusion has now been removed.
