I’m baffled

[shepp]

I was thinking about shooting my 308 suppressed for deer season while I was out test firing a new build I took it with, a box of barns and a mag full of Winchester white box target ammo because the gun has been previously fired to tune the gas block, and to sight in with the new muzzle device.

I fired three banes rounds (supressed) outta it and wasn’t even in the ball park. Switched to the target ammo (after pulling the can off to bore sight) and found the winages was off like 45 clicks….. got it on paper like fist sized group, without the suppressor, put the suppressor back on and it’s shooting far right again like 3-4’. By that point I was out of the target ammo

Im so confused!
 

1 because I shot it when I first got my cans to dial in the adjustable gas block and sight in with the new muzzle device.
 

2 I took apart the can and the gun, no abnormalities in the can that I can see and the upper isn’t loose or anything.

Dpms .308, 18” barrel, banish gold 30 cal suppressor

Check your scope mount.

Scope details, scope mount details, and ammo details.

Since we basically have no information all we can do is take blind shots. 

When mounted is the can in alignment with the bore? Basically, was the barrel threaded to make that happen? 

How is the can held onto the barrel? If it's with an adapter was the adapter removed from anything else and the threads not dressed to clean them up before reuse? That has been known to produce misalignment.

^^^  Good point. 

Neil, how was the suppressor host installed on the barrel?  Crush washer?  Shims? 

 

If it was crush washer, get rid of that thing, and used some 5/8 AccuWashers to mount the suppressor host.

Yes crush washer.

to answer @BrianK, yes I forgot between both shoots, I removed the muzzle device, because I failed to apply rockset, then re installed the same way as I had it before 

So the can screws onto the muzzle device

The gun details, and everything about it -just like we have to "interrogate" everyone all the time, about their certain situation...  You know the drill by now.  You ain't new.

Get rid of the crush washer, first, and buy some AccuWashers and remount the suppressor host.  The crush washer has it on their sideways, because it didn't crush straight.

That will solve 90% of this problem.

Rainy day, spring is coming, swapping out all my crush washers. These accuwashers are freaking amazing, wished I knew about them sooner! I would be willing to bet the problem is more these shitty little shims more than anything….
