Bought a walnut stock from someone on another forum and decided to fit it on my .22 carbine. Went to the farm on Saturday and zeroed at 25 yards. For a change I was really comfortable lying in the grass shooting off a bipod and just for once took my time for each shot. This resulted in the following 5 shot grouping:-
I was very, very pleased with that group! Moved the target out to 30 yards just to see what the drop was and shot this 3 shot group:-
I was on a roll
but surprised at how small the drop was (10mm). hmmm. Moved the target out another 5 yards to 35 yards. This 4 shot group is the result:-
This is probably about as good as I get. I would have extended the range further but that was all the chance I got as I needed to help with farm duties. Again though surprised about the drop of only 25mm.
When I got home I compared this data with both Chairgun's and Strelok's calculated drop. At 35 yards both seemed to suggest that a 40mm drop would be expected. When I tried to put the data into Chairgun to calculate a new BC value for the pellet it basically said my data was wrong. The range distances are accurate as they are tape measured and staked with wooden stakes every 5 yards. My rifle is not overpowered ... I chrono'd it at 573fps (11.66 ft.lbs) before the test and it read the same after the test (in fact the shooting was carried out right at the top of the power curve in where I get 30 shots in a 4fps window). Pellets are AADF in .22 straight from the tin.
When I get chance I shall repeat my experiment but in the meantime what do others get the drop to be at say 35 yards? Are AADFs super slick as they seem to follow a fairly flat trajectory? Overall though very impressed by my .22's accuracy.
