All great feedback. Thanks guys!
I used the 597 .17 HMR as my Ranch ATV gun. It lived in the rack on the Rubicon. I started with a Savage bolt HMR and it worked well. The 597 was just so darn much fun in the dog towns or when you run into a little bunch of raccoons or porcupines! The center fires are just a bit to loud and intimidating for our deal here and I can't bring myself to throw the ole 121 Field Master in that rack.
I picked up a .22LR Marlin Model 60 SN today and stuck a Burris FF2 2X-7X on it tonight. 19" Micro Groove barrel, 14 shot tubular magazine, Synthetic stock, 5 lbs. and yes, Semi-Auto. Used the Laser Bore Sighter that I got on PM "Pay It Forward" (Worked Great, Many Thanks) on it and will try it out soon. Cheaper to shoot. I guess it will work as my ATV gun for now.
I did get my 597 HMR the list for a VQ custom .22 Mag barrel and a VQ trigger job. We will see how that works out.
Again, thanks for all the great ideas. PM is awesome!
