Weasel and I headed out to shoot our rifles again today. We went to the Three Mile Creek range West of Perry…they were open, but had no range master. I called the Box Elder County Sheriffs office and asked them if it would be ok to shoot without the range master present. They said no.
So there we stood for 45 minutes waiting for no-one. Meanwhile another shooting enthusiast came and we left him after he had been there over a half hour. We decided to head over to the Logan range.
These sight in mean a lot at this time of year. For one, my 7mm was not sighted in the last time because I had forgotten to take a tool to open up the vertical adjustment locator. After shooting that time, I came home opened up the adjustment port and cranked it down 20 clicks. I figured at 1/4 inche p/click it would put it down the 5 inches it was too high.
So, back at the range I expected to hit right about an inch high above the 100 yard bull…BLAM….7 inches LOW! I mean below the paper low! My mouth dropped open. I cranked it up 10 clicks, shot 2 shots, and hit about half way toward the bull. I cranked it up 5 more clicks, shot 2 shots and it was still hitting low, but a bit closer. I cranked it up 5 more clicks, shot 2 shots and it was just over top of the bull about 2 inches but all the shots I had taken today were to the left about 3 inches. So I moved the sight to the right about 5 clicks. Let the barrel rest and cool down a bit and then shot 4 more shots, all of which hit between 2 and 3 1/2 inches high and right over top of the bull. I don’t think I can do any better than that the way I shoot. I consider it sighted in.
So, my biggest question: Why did it not shoot exactly where it ended up shooting last time out? It was shooting 7 or 8 inches high last week and I lowered the adjustment down those 20 clicks, which should have been 5 inches of adjustment downward. I shoot and it’s wayyyy low, I end up cranking it up those same 20 clicks and it’s right where I want it…I don’t get it!
The mounts have been checked and they are all tight…Too tight? Is there such a thing?
I was not resting the barrel on the wooden block, I was holding the stock in my left hand and the hand was resting on the block, so barrel float is still ok (or should be).
Do they make scope adjustments that are in bigger increments going in a downward direction than when adjusting upwards? I would think not.
I don’t get it!
Anyway, we also had my 17 hmr to put to the test and it too was way out of adjustment, now it is almost a tack driver at 100 yards.
Then over to the 22 range and 50 yards to sight in the Ruger 10-22’s that both Weasel and I have. Mine required just a bit of adjustment to bring it home at the 50 yard line. Weasels adjusted in quickly from its newly mounted scope and bore sighting.
So, all the rifles are ready for action.
