My name is Tom Lewis, I live in Carlsbad NM. I am a retired teacher and have made hand made knives for 40 years.
I have a Gamo 21 .177 air rifle with a Leapers scope. When I sight it in it holds 1/4" groups at 30 feet. The problem is when I leave it for a week or so and then shoot it, it is off a couple of inches at 30 feet. It doesn't seem to hold it's accuracy. I have tightened all the screws and bolts.
Any ideas and suggestions will be appreciated.
