Zero with a range finder

I was given a friends range finder to get my zero sorted with my Stealth and went about doing so this morning. It was bloody cold but the wind was very light so it made sence to get it done.

I am shooting a .22 Bis Mag (21.4g) with a 24 inch barrel, Drums hybrid hammer, Expert HPA reg at 1500psi and a 48CU tank.

I am getting 783FPS with only 3FPS spread and more shots to one charge than i can be bothered to count.

16 yards 3.4cm / 1.3″ below X
21 yards X
26 yards X
31 yards 1.4cm / .5″ above x
36 yards 1.1cm / 4″ above x
40 yards .5cm / .2″ above x
45 yards X
50 yards X
55 yards 1.7cm / .6″ below x
60 yards 5.1cm / 2″ below x

then the battery on the range finder died 👿

It is a bit different to what chair gun thinks so i will have to adjst the BC and see if i can get it to match up a bit better.

gonna draw up a bunny, squizzer and pigeon head on a bit of paper and stick to to that massive bottle on my Stealth with aim poins marked out for the distances out to 130 yards. I recon foxed are game out to about 30 yards but i dont see that happening in a rush.
