RE: .17 hmr ( help pick)!!!!
I picked up the CZ-452 American last year in the .17HMR caliber mainly for a super accurate squirrel gun at ranges up to 75 yards. While this gun groups fine at 50 yards,that little .17 gain pill it has for or a bullet, at 100 yards, it's not quite the shooter I was hoping for. The wind plays havoc with that little round at that distance with any wind what so ever.
I'm seriously thinking of going back to a good quality, super accurate .22.
This round isn't cheap at $10.00 per 50!!
That new .17HMR2 might be the ticket though!!

Comparison between the 17 HMR 17 and 20 gr ammo. The 20 gr XTP bullet's BC was backcalculated from Hornady's drop chart. I included the 17 HM2. Using the muzzle velocity quoted by
Hornady and the muzzle energy, it indicated that the 17 HM2 uses the same bullet as the 17 HMR.
LOSE 66.5 YARDS WITH THE 17 HM2.... Notice that the 17 HM2 velocity is similar to the 17 HMR velocity after the 17 HMR has traveled about 66.5 yards. Or in other words, the 17 HMR gains you about 66.5 yards over the 17 HM2. With the 17 HM2 you have to move 66.5 yards closer to the target to be equivalent to the 17 HMR. Assuming a 1-9" twist, the exception is that the spin velocity of the 17 HMR bullet will remain about 204,000 RPM (spin energy of 0.44 ft-lb) down range and the 17 HM2 bullet will be 168,000 RPM (spin energy of 0.30 ft-lb).
SOUND VELOCITY.... The velocity of sound in air is approximately 1130 feet/sec. or 770 miles per hour at room temperature of 70 deg F. The speed varies with the temperature of air, such that sound travels slower at higher altitudes or on cold days.
Notice that the 17 HM2 energy curve would fall on the 17 HMR curve after about 66.5 yards. Also note
that the 22 LR has more retained kinetic energy past 210 yards than any of the 17's. But even with
the higher retained energy, you have to be able to hit the target for it to accomplish anything

read the charts do your research and you should have a very good idea on what rifle suits you better
ive said it before my marlin 17hmr with bull barrell shoots great and when coon or other small game you can see the impact through your scope due to it being quite fast and low recoil
check out this web site http://www.varmintal.com/ahunt.htm
there is a lotta good stuff here

What I "like" and can "afford" are two different things, but here's what I'd like from Volquartsen (and the Cooper's aren't too bad either):

It might help to decide what kind of action you like best (break, semi-auto, or bolt), then start narrowing the manufacturers models given your preferred action type.
