I remember buying 22 long many,many years ago. I agree, I haven't seen any lately. Maybe there just isn't any need for it.
I was in an arguement with someone saying their Coey Model 60 will only shoot 22 long. Tried to explain how LR is the standard and will be just fine and if they did manage to find any 22 long it would not be cheap. But why let the facts get in the way of a good arguement. Lol...
Long Rifle is the standard now, but that doesn't mean it was always this way. My understanding is that 100 years ago all the variants of .22 rimfire (Long Rifle, Long, Short, BB and CB) were all very popular. I've read more than one old report that many people shot shorts most of the time, because they were cheaper. I don't know about the Cooey 60 specifically, but I'm sure there are guns out there that will shot .22 Long but not LR. I know there are Beretta pistols that will only shoot .22 Short.
Recently saw a video where it was explained that longs are not made anymore because new shooters kept confusing 'long' with 'long rifle' and after trying to shoot longs would appear in gun stores complaining their new semi autos weren't operating properly
I probably have it muddled from more than 50 years ago, but quite sure my Dad would get Longs or Long Rifles, pretty much interchangeably, for his Cooey 60 that I learned to shoot with. I seem to recall the labels were Dominion or perhaps Imperial. As I recall, a "Long" was a "Long Rifle" case, with a "Short" bullet. Back then, BB caps cheapest, then Shorts, then Longs, then Long Rifle. Dad said when he was a boy - 1930's - that all they ever shot was the smaller BB caps - never could afford even "Shorts"...
The Cooey 60 will shoot, Long, Long Rifle and Shorts, it is tube fed, I have shot all through mine. The Marlin 60 will do it too.
