I'm hoping its just the ammunition and not my rifle itself. I have a friend who's had the same problem after he got a suppressor fitted to his rifle, he figured out that his barrel wasn't quite set properly in the stock. Long story short he got it reset and all is now fine and he hasn't had the same problem.
But for me, I got my suppressor fitted quite a few packs of ammo ago, so I think its just the pack of ammo.
Thoughts?
Cheers everyone
