Bbasi: Great shooting there!
That grouping makes me want to try those 20 grain Hornady V-Max bullets in my heavy barrel 17 Remington Fireball (and in my custom Varmint Rifle in caliber 17 MachIV).
Checking my loading log it appears I have not tried 20 grain bullets in any of my 17 caliber centerfire Varminters.
Very few Rifles/caliber combinations provide as much satisfaction/fun as a heavy barreled 17 Remington Fireball in a good colony of Ground Squirrels!
Thanks for sharing.
Hold into the wind
