I went to the Emerald Empire Gun Club range today at McGowan Creek near Marcola. Nice setup they have there and super nice folks shooting there. I was sighting in a few rifles: Savage 93R17BTVS .17HMR Savage Mark II Classic .22LR Savage 12 BVSS .22-250 The .22-250 is truly the most accurate rifle I have ever fired. My initial 3 round group was 2" high and 6" right. I adjusted my Nikon Buckmaster scope the estimated number of clicks and the next shot was dead center of bullseye at 100 yards. The next shot was touching that one. The next 3 were within 3/4". The Mark II performed as expected - about a 2" group at 100. Now the 17 HMR gave me some trouble. I started with Federal Premium 17 Gr V-Shok ammo. I fired five 5 round groups and could not get any amount of consistency - we're talking random 6" spread, despite the crosshairs being on the same spot, even with follow through after the shot. I switched ammo to CCI 17Gr TNT and was able to immediately shoot sub 1" groups. What is the deal with this Federal Ammo? Anyone else have similar experiences? I know the Hornady stuff has worked well for me too - I was hitting empty shotgun shells at 75 yards the last time I went out.
