RE: Savage in 17 HMR?
One of the savage sporters with the plastic stocks probably go for that. Or you could look at used if you can find one.
I own a savage heavy barrel and love it.
As much as I love my 17 though I'm not sure it will work a lot greater than your 22 mag. What kind of loads were you using. Your success could be better if you tried a different style of bullet. Providing it was accurate enough for your needs. They make a 30 some grain Vmax bullet for the 22 mag I think.
The 17HMR would give you a bit more range because it shoots flatter, and they are generally a bit more accurate. I'm not sure what load I would suggest for turkeys though? I don't know if the 17 grn v-max would be better or the 20 grn XTP's. The V-max's may cause too much meat damage on a body hit, or may lack penitration on a turkey. We can't hunt turkey with a rifle here so I can't really tell you for sure.
If you don't get any deffinitive replies here try Rimfirecentral.com. They have a 17HMR forum and I am sure someone there has hunted turkey with one.
I do know that if they made it legal here I would have no problem taking my HMR turkey hunting. My gun is very accurate and pretty darn flat out to 120-130 yards. The only problem would be the wind.
