Tom: I currently own 17 caliber Rifles in the following calibers 17 Mach2 (2), 17 HMR (3 and one S&W revolver), 17 MachIV, 17 Remington Fireball and 17 Remington (3).
In addition to these Rifles (and the one 17 HMR pistol) I am currently dealing on a used/as new Ruger 77/17 WSM V/T and I have been searching high and low for a "deal" on a Ruger 77/17 Hornet (I already have the dies and two packages of brass for this caliber!).
I am a 17 caliber enthusiast to the nth degree!
I highly recommend you get started with the fun and efficiency of the 17's.
Further I recommend you get both a rimfire 17 (preferably a 17 HMR - an OUTSTANDING round!) and a centerfire 17 to compliment it (17 Remington or 17 Fireball).
Try one (or two!) I know you will enjoy them.
Hold into the wind
