I like Taurus revolvers myself.Had a Tracker .17 and still have a Tracker .22mag. They are 6.5" barrel plinkers I picked up cheap.I wouldn't carry a .17 for a back up,I carry a .357 snubbie.I have carried my PMR 30 though.I can pump out 60 rounds in about 15 seconds with it.
I've got a Winchester Model 94 in .17 HMR and I really like the round. I've witnessed some exploding prairie dogs with it (never saw that with 22s!). Ammo isn't too bad, as I can find ammo as low as $10 for 50 rounds (I just bought a box of 500 for $100).
I had one in stainless and sold it. Missed it and bought one in black from the kidd. It is a straight shooter. No recoil at all.
I have a thumb hole stock, stainless bull barrel savage in .17 HMR as well. Tack driver.
My buddy was shooting it and popped (literally) a tree rat with it. Not much left to eat.
