Today is a beautiful day in Western MB, so I figured that it was time to go to the BWA Range and calibrate my new-to-me Rossi pump .22!
My task for the morning was to calibrate the rear sight graduations to some .22lr Federal Bulk ammo. At 25m here were my results, with graduations from lowest to tallest, back to front:
1 - 3.5" high
2 - 3" high
3- 5.5" high
4 - 6" high
5 and 6 - not tested.
As became evident, this rear site allowed compensation to a rather long distance. So I tried my hand at 50m with the federal, an the first notch..it was still high. On the photo below, the holes at the top are the federal.
So I figured that low velocity ammo would work better. I dug out some CCI Subsonics and hit point of aim at 50. These are the holes below the line.
The groups, if you can call them that, are not that good. In my defence, I was getting hungry and my mind was wandering.
I really like this pump gun, and am looking forward to trying some longs and shorts in her. And of course some tree rats!
Cheers
