Things aren’t always as they seem. I have switched pellets from Gamo to Crossman, most recently to use up a partial container. I sighted in my rifle and then I went on with my day. A couple of days later, I was shooting offhand and I saw that my group was terrible. I had been shooting offhand with the Gamo pellets within a 2 inch group, sometimes even within a quarter.

I am shooting offhand on purpose. This is training for hunting. Sure, if you can have a rest, then it is better, but most deer I have shot have been without any sort of rest. So, this is finding the scope, trigger control and breathing.

At first, I thought it was the pellets, so I shot on a rest again and I was getting quarter sized groups. Then I thought it was possibly my eye sight. The group above had one group (of five) with my glasses off and one group of five with my glasses on. They were not great so I decided to try this experiment again with deliberateness.

This time, whether glasses on or glasses off, the group was all together, so I decided to look deeper. I noticed that the scope had slid all the way back on the rings. When I went to loosen the hex screws, they were already loose.

I have heard that airguns are hell on scopes. Just this week, I also tightened up the metal to the stock. Now, the scope was loose. I am happy to say that things are back where they should be. This is the first ever recoil induced failure I have ever observed.

I am one of those fix it once, right kind of people. So far, I have only just re-set and tightened everything up. But without doing something different, this is going to happen again, so maybe I ought to use some blue Loctite.

End Your Programming Routine: As I said at the beginning, things aren’t always what they seem. I still believe that there is some more variability in the Crossman pellets. They do not seat tightly and my groups are more open than what I have been shooting with the Gamo pellets. That being said, my first clue should have been the adhesive pad backing out from under the scope mount. I didn’t know why that was happening, but now it seems like it was the scope moving.
