Thread: suppressor strike

I dont know the twist rates. reloaded ammo, one was a 7mm rem mag threaded by a good gunsmith but second hand suppressor. recently a .222 brno which was set up by the previous owner. I have used it for a couple of years , but did just change bullets.Only changed bullet weight slightly though . only just noticed the wee nick in the supressor when putting it away ,so dont know where to go from here. the gun hasn't had any knocks or anything. Haven't been heavy bush hunting , so unlikely to have foreign matter in the suppressor .

I guessing the Rem mag "blew up " & left your "ears ringing" ???

"the wee nick in the suppressor" on the 222 was likely a tumbling projectile as 222s generally have an extremely slow twist

yes correct greg. it was the rem mag that blew up. i will try switching back to the same old bullets on the .222 . they were shooting fairly accurately , so didnt seem to be tumbling ?

take suppressor OFF and try the loads without it...are they tumbling or printing nice wee clover leaf groups... that will sort out if trebly dont like the load...

Could it be a low flash point cleaning fluid or even grease that has become boiling hot, that has flashed as the suppressor heated up, and after buying up between shots, exploded on the next shot?

I was going to say something along these lines. Even unburnt powder depending on what's going on... slow burning powder gets mixed in with grease or fouling, won't flash off under normal circumstances but detonated when everything's just right.

Exploded can mean all sorts of things, but if it's a detonation and not just a strike causing the suppressor to blow apart, then that would imply overpressure.

.222 can generally only stabilize light weight projectiles, so if you are running anything above about 55gr in the .222 you may start running into stability issues.
