Marrakai - that is interesting, I did not know the year that the long ctg. was brought out.

Here in NA, .22 short specific rifles had 24" rates of twist that ctg's. short 29gr. bullet. The .22 Long today, having the same 29gr. bullet loaded to the same speed as the short, also should have the 24" twist.

The .22 LR though, with the longer, heavier 40gr. bullet necessitated a 16" rate of twist. Thus, .22 short or .22 longs do not shoot as well as .22 LR's, when fired in a short, long, long rifle marked rifle, as that rifle will have a standard 16" twist.

By the same token, a .22 short specific rifle, if re-chambered to shoot long rifle ctgs. will not shoot accurately as the rate of twist is too slow for the longer bullet.
It may, however, shoot some of the newer hyper velocity .22 LR's with lighter bullets at elevated speeds.
