I think the .22 LONG was made prior to the .22 Long Rifle. The chart or listing above shows .22 Kurtz and .22 Lang, short and long & they appear to be loaded with the same bullet, not the longer LR bullet.
The cases of the .22 Long and Long Rifle were the same length, however the bullets of course are different - 29gr. for the .22 short (Kurtz) and .22 long (lang), and 40gr. for the more modern, .22 Long Rifle.

Barnes COTW lists the .22 Long Rifle as being developed in 1887 by the J. Stevens Arms and Tool Company.

"It is the 22 Long case with a 5-grain blackpowder charge and a 40-grain bullet instead of the original 29-grain."

Also- if chambered for the 29gr. Long's bullet or the .22 Short ctg. the rifling twist should be in the 24" range, while the .22 LR rate of twist became 16" - however - when the twists were straightened out to those standards, I do not know. Only measuring will tell. If indeed slow, it will shoot the long ammo just fine. If the faster twist, it might not shoot the long ammo well at all, which would be fine - LR is much cheaper - here, anyway.
