I bought a CVA Firebolt last week and I put a Simmons 8-Point scope on it and had it bore sighted for 100 yards,the scope is mounted on over-under rings.Well, when I took the gun to the range to"Fine tune" it I couldn't get it to even hit the 100-yard target,so I went to the 50-yard target and it wasn't even hitting that.Well after about 5 or so shots I decided to put the guns sites on the target and adjust the scope to the target that way and I finally got it to hit the target at 50-yards but it was high so I adjusted it and went to the 100-yard target and I still couldn't get it to hit the target.Does anyone have any kind of pointers about how I can get this d**m thing Zeroed???PLEASE HELP.
