Range day was great. Or so I thought until I tore everything down for cleaning… Range day before this one I had issues with some 50g fiocchi keyholing out of 3 different rifles… My mk12 just happened to have my sandman S on it as well… Luckily this is not a baffle strike, but the ebrake and front cap however is a different story… That’s $200 down the drain…
Pretty sure this was a Covid batch of ammo I’ve had for a while. Pretty sure it was all short loaded powder judging by the issues it was creating with all 3 rifles short stroking
I don’t know anything about suppressors, but despite the hole not being perfectly round any more, it looks like it could still be usable? Or is it damaged such that the hole is no longer in alignment with the barrel? For $200 I’d be thinking about reaming the hole out to continue using it
I’ll continue using it on the 556 guns for now but I won’t shoot any 308 through it until it’s replaced. It didn’t strike the flash hider, but when it made contact with the ebrake and did the damage in the picture it shot a piece of projectile into the back of the threads for the end cap and damaged it. Getting the cap on and off is very difficult now but not impossible. I’ll have to replace them before I put it back on the 308s because the hole is no longer concentrically round. The 556 is small enough it won’t matter, but I’m sure the bolt actions will end up making contact. As it is it doesn’t appear to have hurt the suppressor itself, but if I launch the end cap off it will likely damage the threads on the end of the can body, and then that would require a trip back to dead air for repair under warranty. I could take the ebrake off and put the other .30 cal end cap back on it for the bolt guns but will lose some flash suppression on hotter rounds without the ebrake
The Sandman series have removable end caps so you can change them from 556 to 762, but I always just leave the 762 parts in it to keep from forgetting when I swap it from rifle to rifle. The ebrakes are add on parts that screw in-between the end cap and the can body and then you screw the end cap onto the ebrake. It essentially gives you an extra chamber at the end of the can that is vented to allow the tiny bit of flash to burn off inside the ebrake instead of shooting out behind the fired projectile
Started at 20 yards, moved to 7 yards and 10 yards, finally taking a step left or right. The more wild shoots were from 20 yards. Also on the bullseye I was doing 10 rounds in 10 seconds at 5 yards.
