I messed around and wound up with a sporter weight 17 HMR barrel for the CZ455 Varmint,,it looks funny with the light barrel in the varmint stock but with the 4.5-14 LR/T M1 scope and a 100 yard zero the 17 gr VMax bullet is only 3/8ths an inch high at 65 yards and 1 inch low at 125.

I may get up Saturday morning and give it a try,,I havent been all year yet..anybody use the HMR on squirrels,,I have the 17M2 but havent ever hunted with the Magnum,,we will see I guess,,I bet it makes a mess.
