Thread: Rookie mistake

Was shooting this afternoon. Thought all was going well first 2 shots around an inch apart. Then things got weird. Groups started jumping around in 2's.

Thinking something must be loose had a look over the rifle and realised I had the wrong Bush in my suppressor as I use it on 2 rifles and the other rifle has a bigger barrel so Bush was loose.
Wasted a few round and will have to head out again tomorrow. Hopefully out as simple as that.
