Very recently I did some changes in my Leshiy2 powerdrive with .22 MRD's in my mind, changed the jets (2x0.5) and tuned the Reg to 135 bar.
The goal was to have the most air-efficient tune for 920-950 speed. Slugged the .22x600 Superior (1:24) and resized one tin to 5.22.
Kind a busy or lazy these days but today I visited my club, the 50 meters range. Here are my findings:
4 shot groups into each rings, 50 Meters, slight some airmovement so who cares until I can read the ghroups.
The circled with yellow and blue was shot with my 8-32x60 Nikko. Just saying.
The yellow marked rings are MRD's weight sorted only and not resized.
The blue marked rings are resized to 5.22
And the red marked rings are back straight from a tin but shot with 1-6 LPVO.
What is a point with the picture?
-3C and 76% humidity
What I didn't expected the resized pellets will shrink to an extent that the 5.52 may even got loose in rifling, and as we can see the groups (of 4 marked in blue) opened up. So nomore shooting "undersized" pellets over winter and need retesting next summer.
The EazyFill orings shrink and I was loosing air abnormally to be able to top it up. I must find some oversized orings (my very first idea) because usually the Canadian winter gets way lower Temp's than today.
I got 6 mags from 280 bar down before reached the Reg, from a 300cc bottle, and I guess I may sqeeze in the seventh mag if warmer day.
And I promised myself LPVO from now on for three rats only and below 20, I cannot see sheit with that scope @50.
And the most important maybe, I need to ask my wife where she boxed last time my thicker winter socks.
