I'm a believer,,,
I have a Model 34 J-frame in .22 LR and a Model 36 J-frame in .38 Special,,,
I do believe that practice with the .22 translates to better proficiency with the .38.
If for nothing else than I would have never been able to afford the equivalent amount of ammo for the .38.
One thing I do recommend though,,,
Shoot the .38 as well.
My typical practice routine is 50 rounds of .22 and 5 to 10 rounds of .38 Special,,,
My thinking is I need to remain very familiar with the extra recoil of the .38.
Just a few weeks back a gentleman posted about his experiences with his pair of Ruger LCR's,,,
He also felt that practice with the .22 translated to proficiency with the .38.
Your mileage my vary but I believe it has worked very well for me.
