I'm personally convinced the .22 Magnum is a rifle round. It loses too much velocity and is just too loud out of a handgun for me. I have zero use for anything in between .22LR and .38 Special, but that's just me.
Over 2000/fps in a handgun isn't enough velocity?
As far as loudness goes I don't see where any caliber larger than the 22mag is quieter.Pop a few rounds of 22mag at an intruder in your house and he'll make a quick exit not waiting around to see what's in your hand.
The PMR-30 will never shoot a .22 Magnum to 2000fps. Not even a hyped up 25 grainer. 4.3" barrel, you'll get 1200fps with most loads. Sorry to burst the bubble.
Your estimated fps is low and on my side there aren't but a few brands of 22mag that even say they are 2000+/fps.There are numerous videos on Youtube where someone tested different brands for velocity.
Depending on what ammo was shot I saw results ranging from middle 1300/fps to 1650+/fps.A Henry 22mag didn't do any better than the best result in the PMR30 so I would say the PMR30 did pretty well even with an average drop of 250/fps under what the rating on the ammo box might say.
Bottom line...I like the PMR30 and you have no use for it.
