Did a little test a few days ago just for fun but it's one that I have wondered about for some time.How much velocity is lost when you switch from a Rifle to a Handgun?
Tested the 22Magnum and the .22LR. Here is what was found.
For the 22LR Rifle; a Brno #1 (23.5" barrel) was used and for a pistol; a Ruger Mk 2 Target. (6 7/8" barrel)
For a 22WMR Rifle- Savage 4m deluxe (22.5" barrel) and a Ruger Single Six (5.5" barrel) for the pistol.
All velocity was based on a 5 shot average over a chronograph placed 10' from the muzzle.
1) Brno #1 22LR shooting CCI Standard Velocity yielded 1,070.2 FPS. Advertised velocity for that load from CCI was 1,070.
2) Ruger Mk2 Target shooting CCI Standard Velocity yielded 963 FPS. Again. Advertised at 1,070fps. (Subtract 51FPS for this load in the single six with 22LR cylinder.
Total velocity loss of 107 FPS between rifle and handgun. Not too bad.
1) Savage 4m Deluxe 22WMR shooting CCI MaxiMags came in at 1,948FPS. Advertised Velocity from CCI was 1,875 FPS.
2) Ruger Single Six shooting CCI MaxiMags produced 1,351 FPS. Again advertised at 1,875 from CCI.
Total velocity loss in the 22magnum from rifle to pistol was 597FPS. This was surprising and a little disheartening as I'm a big 22magnum fan. I'm not sure that the extra noise, and cost of ammo is worth the extra 388FPS. I would be curious to see if some of the 22magnum loads optimized for short barrels fare better.

In a 22LR, max velocity is reached in 16-17". After that, it s lows down.
I have stuck Super Colibri bullets in the barrel of my CZ. Yes! Do not shoot any Colibri's in a CZ. They won't exit from my 452.

I believe the .22 mag was designed for a rifle. I had a ruger single 9 (.22 mag only) and there was always unburned powder around cylinder. Haven't shot any out of single six convertible so not sure if it does the same
