I have a Colt 16" Match Target. It is about a year old and has had less than 1,000 rounds through it.
I have a 100 and 160 yard range and two weeks ago I shot a 20rd group at 160 yards that was about 4 to 5". A group that I was very pleased with.
I ordered a scope mount, Armalite, and it arrived yesterday and I took the handle off last night and mounted a Leupold 1.75 x 6 Vari X III and couldn't wait to take it out this morning.
I sighted it in at 25 yards and I was making a jagged hole at 25 yards with 5 shots. They were all going in almost the same hole. When I started shooting at 100 yds to my surprise I wasn't even hitting the paper. So I put up a bigger piece of paper, 24 x 24" and still wasn't hitting the paper.
I tried Winchester Q3131A, PMP, Winchester 62gr power point, and Federal 69gr Match ammo. Ocassionally I would hit the paper maybe 2 out of 10 shots. I noticed that some of the holes were kind of jagged. After having shot another 10 shots, I hit the paper three times, I noticed that one hole looked as though someone had laid the bullet on its side and pushed it through the paper. I believe that the bullets are tumbling before they reach the target at 100yds.
I know this is not logical, but could taking off the handle and mounting the scope on the receiver have caused this problem? I looked at everything and that is the only thing I have done different. I was shooting off of sand bags to.
Does anyone have any ideas what is causing this?????
Any and all thoughts and suggestions will be greatly appreciated.
