DIY boresight & 10/22 range trip with rimfire scopes
Posted: Tue Jan 19, 2010 9:01 pm
Took advantage of recent warmth and took my Christmas 10/22 to the range. Before I went, I did some cheapo "boresighting" on my two 3-7 X 20mm scopes.
I propped up the barrel/receiver, with scope, with some books on a kitchen chair. Using a dental mirror, I aimed the bore at an orange target dot I stuck on the wall at the end of the hallway. I then carefully set the scope on the dot as well, double checking the bore aim as I went. Then I did the second scope the same way. Then in curiosity, I looked and saw the open sights were pretty close, too.
Then the range trip. Sure enough, the open sights were dead on at 50 yards, right from the factory. Thank you, Ruger. And, the Weaver TO-9 mount was low enough to use the sights easy enough.
When I mounted each scope, i thought to drop them down about an inch worth of clicks, since they were set up in a ten foot hallway.I aimed at Pete the rubber prairie dog's chest, and got him with the first shot from both scopes. I was surprised my hallway boresighting was that close. They were still about an inch high and a few clicks off on windage, but it only took about 40 rounds to be sure both were fine tuned to my satisfaction.
The Tasco 3-7 X 20 scopes surprised me. They have good definite clicks, and a clear view up to 6X. The 7X is a tad blurred at the edge. And they held zero just fine when removed and replaced. They are good quality within the limits of their design. Not bad for $18.
