Ran some .22's

[Kurt]

Jim I think with the .22 coming back down into the subsonic has to do a lot with the weight of the bullet. The heavy .38 to 50 we use for black powder I think hold the shock better I think then the light .40 grain that really gets bounced around breaking back through into the sub or the wind at super the wake around the bullet is what pushes it more than in the sub and the high power holds better at HV because of the faster rotation they get acts like a gyroscope holding it true in flight and gets to the target faster holding the drift down.
I agree testing the powder rifles at ranges less than 300 is of not much use for long range. 200 yards is a start but you need to get past 300 to get the best from your loads. The .22 used for 200 yards one better test the rounds at 200 yards. 25 or 50 yards is not the answer what it will do at 200 but it will show at 50 the priming will be good. The priming is what effects a rimfire round and you also see this with centerfire primers.
