Here is what I have going on, I have a field/deer combo mossberg 500. The rifled barrel is NOT a cantilever- I have a scope base on the receiver. I am 99% sure the scope base and scope is not the issue. I tried shooting slugs (3 different brands) but am getting shots all over the place. Sometimes it will group for 2 shots then it moves a (I’m talking sometimes feet at 100 yards).
I pulled the barrel and tried to shim the barrel/receiver connection, and I think it helped a good deal, but still getting 8” groups at 100, until the group walks off target.
I’m thinking the connection between the barrel and receiver is the issue.
Does anybody have any recommendations? Drill and pin the receiver? This is going to be a dedicated deer gun. If the receiver was steel I would just have welded it together..
Any thoughts or advice is appreciated
