Keep in mind that all Match .22LR should be subsonic. Match in much of the world means 50 meters and many "Hi-Speed" .22LR would drop from supper sonic to subsonic at about 40 yards and wobble slightly. Even the Hyper velocity do this around 100 meters.
Most American .22LR Match stuff used to run around 1040 FPS at sea level 70F and 70 % (used to be called standard weather, would be nice to live where ever that is standard weather, eh?) Euro stuff ran around 950 FPS.
In high school we used the old Super-X copper wash for training at 50 feet because it was still super sonic when it splattered on the plates. The Target and Match Ammo was noticably quieter without the sonic crack.
This was all Round Nosed 40 grain solid .22LR in match rifles.
BTW the ISU 50 meter prone target had a nine ring smaller than a dime or old 50 pfinig piece and shooting less than 90 from unsuported prone was considered shamefull. So you see accuracy was more important than velocity,
,22 Short also came in two varieties, Standard velocity and high velocity. Again the Standard velocity was what got used in guns like the .22 Short version of the High Standard or the Walther turning target guns or a host of target revolvers used at 25 meters or less. High Velocity shorts were for hunting and such and while generally still subsonic seemed louder and more likely to be found with Hollow point pullets in my day. In fact a buddy that had to carry a Beretta 950 to keep concealed at his job had trouble finding in the 1980s High Velocity short solids, his choice for Self Defense being penitration over expansion in such a small round.
of course actually there was a third choice in .22 Short that was hard to find....Gallery Special that used a fragmenting pressed wax and clay bullet. State side I never saw them out side fairs and carvivals (and never failed to use some up when I did, Carnie tricks or not, guess I was a good mark for those guys) in Europe I saw folks using them on indoor ranges and the most interesting use was in a High Standard rapid fire .22Short pistol that had a suppressor and actually cycled the things! The owner was a clock repair man....as in city clocks of the 1500's up. He claimed most clock issues were pidgeon related. First thing he did was smoke a cock tower machine room, then block any holes he found then shoot down pidgeons that had stayed through the smoking with those Gallery Specials. He said the bullets shattered on 500 year old stone walls without ricochets. Most of his actual "repair" work consided of placing a coin on one lever weight or some such and pushing it about to get things balanced. He said some clocks had coins about as old as the original clockwork on various structures. The pistol also worked fine at the turning target game with standard shorts where I had difficulty detirmining where most of the noise came from, the action cycling, the report, or the bullet slap into the back stop. He seemed to make a good living and finance his shooting hobby quite nicely.
Both Shorts and Longs used a 29 grain bullets and my understanding was the long in Black Powder days was just a way to get what we now consider High Velocity short speeds.
Typically CBs and CB longs use 29 grain bullets and the only reasons for the CB Long are for use in a LR chamber to prevent that built up ring we were discussing and to get the bullet closer to the lead of the rifling to allow less free bore and theroretically better accuracy.
...and I am tired of typing.
