Gettin' kinda serious. Gonna take a drive along the Blackfoot River canyon and see what I can spot. I know there are chucks back there and ranges would be as long as one wants.
Also there are patches of very numerous ground squirels. They're a tougher target than the chucks.
Just for grins here's a target from yesterday with the new LR Varmint rifle.
Shots 22, 23, 24 and 25 with 77, 77.5, 78 and 79 grains of W760 for velocities of 2458, 2486, 2498 and 2510 respectively with the Hornady 300 gr BTSP out of the Ruger #1 375 H&H.
after 25 shots off the bench with that thing I'm wondering if some one makes an 80gr 22 cal sabot for it.
I'll let you know if I find a good chuck spot.
