Hammering it home

dime_novel_heroCQB Brutality East is coming up in just two short weeks and my performance in the Cabin Fever Challenge has taught me that using Kentucky Windage to adjust my Rossi 92 lever gun shooting 7 inches to the left at 100 yards just isn’t going to cut it. To that end, I purchased a Bushnell Laser Bore Sighter, hoping to make adjustments in a proper basement workshop instead of in a slipshod fashion at the range.
That did not go according to plan.
I made an adjustment, set up the laser sight, felt it wasn’t lined up, made another adjustment. Eventually got a sight picture that I thought was pretty good. I did, however, feel a little itchy, thinking that I had moved it too far.
At the State Game Lands rifle range I set up several targets at 100 yards and. . . sucked.
Where before I was shooting 7 inches to the left at 100 yards, I was now 10 inches to the right. My itch had been correct. So, I went back to my car and got my “just in case” hammer to make additional adjustments. I also moved to the 25 yard range because there were not as many people shooting there so I would have more chances to go out and check my targets.
With a brass punch and hammer, I gave the dovetail read sight a few whacks and moved it back towards the left. I fired ten more rounds and was better. I moved the blade down a click to try to pull it back onto the paper, gave it a few more whacks and shot another string. In all, I shot six strings of 10 rounds and ending up with something that was much, much better.
I know the group looks a lot tighter, but that’s the difference between shooting at 100 yards and at 25 yards. Mathematically, the MOA (Minutes Of Angle) of the groups are pretty close to the same. More importantly, and the objective of the endeavor, I had moved the horizontal deviation from 10.23 inches to the right at 100 yards to what would be 0.08 inches to the left at 100 yards.
That makes me very happy.
It still shoots high but I can’t move the rear sight down any more so I will just need to shoot at the bottom of whatever target I am shooting at to keep the impact on the plate. And that’s a group shooting from a sandbag. My group shooting offhand will be much looser but that will be all on me, not the gun.
With the weather getting nicer, I will move my dry-fire practice out into my back yard, affording me the opportunity to do some running back and forth.
