Alright so I sent in my sparrow for the SS upgrade and I have been seeding my lawn and now I have to defend my seeds from the invading birds. The only small bore can I have is my M4-2000 so I screwed it on my 22lr and fought them off, inflicting massive casualties in the process. 10 rounds = 10 confirmed kills.

I know that I am not suppose to because the powder and lead build up, BUT how many rounds is too many rounds? Because $2,400 worth of HydroSeed is going to be protected.

I cannot use the .223 because the sonic crack. My only neighbor for miles lives on the same driveway 100yds away in the other direction and do not want to wake them at 4am.

Also that thing is freaking quite. All you hear is a tic. Pretty sure it is quieter then dropping the firing pin on a empty chamber. At least it sounds like it on my bolt gun.

It is difficult to quantify how much is too much. Like everything in the suppressor world there are a lot of variables - how hot you get the barrel, type of projectile, type of powder, barrel length, etc.

You might get some buildup in the suppressor but it honestly won't hurt anything unless you are shooting a lot of 22s through it. If lead accumulates in the suppressor from the .22lr rounds, much of that will vaporize when you get the suppressor really hot with a "mag dump" or two of 5.56 ammo. Some powder fouling can even blow out.

I wouldn't shoot .22lr through my personal 5.56 suppressors if I had the choice of using a dedicated .22 suppressor I could clean. But a few hundred or even thousand rounds isn't going to hurt anything.

Some people on gun forums really overplay the lead buildup issue in this case (.22lr through center-fire suppressors). I think many people have no personal, first-hand experience and instead just regurgitate what they've heard from other people. I have friends who regularly shoot .22lr ammo through their 5.56 suppressors using conversion kits on their M16s. We've even weighed the suppressors after a full day at an MG shoot then weigh them again after a couple full-auto 5.56 mag dumps. With extended use the 5.56 suppressors do fill up with carbon. But that happens even with 5.56 ammo. And there is no doubt you will get some lead accumulated that won't blow out.

Bottom line, some .22lr through your 5.56 suppressor isn't anything to freak out about and it won't destroy your suppressor. It isn't advisable to shoot a lot of .22lr ammo through your 5.56 suppressor, but minimal use isn't something I'd worry about. If you are only talking about a few hundred rounds through a rifle I wouldn't worry.

Last rambling comment...

This is a bigger issue on pistol suppressors that use recoil boosters. Why? Because added weight in the suppressor can cause problems on the pistol host. Problems can include damage to the suppressor and/or host firearm. There is no way I'd put rimfire ammo through my pistol suppressors.


That is my take on it. I am sure some others will have different experiences and/or opinions.

Thanks, that is the kinda info I was looking for. It wouldn't be a issue if the seeding didn't cost so much. I don't see to many rounds have to be fired. Usually 3 or 4 shots then they fly off for a few hours then come back for 3 or 4 more.

I would guess that I will have a box or two shot by the end of this ordeal. Not too much but just didn't know. I can do a mag dump or two a few times this week too if it'll help burn the carbon out.

After you shoot one of them hang it up as a message to all the others to beware of owner...he is a killer. Or, decapitate one of them as a real message and hang its head on a stick. They will get the message
