I recently purchased a Ruger American Gen II Ranch 16 inch in 22 ARC. (1:7 twist) This thing is a tack driver! After bore sighting, while zeroing, I thought I missed the paper at 100 yards with my second shot but after a closer look I one holed two shots and was .25 in off on the third. I repeated nearly same thing on the next 3 shot group. This was using Hornady ELD Match 88 Grain. Next I shot a few groups with Hornady Black ELD Match 75 grain and those did well too. The 88's had a better SD and ES. I'm going to use the once fired Hornady Brass to start working up some loads. There isn't tons of load data out there for that round yet so I'm looking for some powder suggestions. I bought some Hornady ELD-VT 62 Grain and some 75 grain ELD-M bullets for this rifle I also have a lot of other options in my inventory. I want to use a temperature stable powder that is good with heavier for caliber bullets. I plan on the replacing my 14 twist 22-250 so I can use heavier bullet. I am thinking about trying some TAC, Varget and CFE 223. (CFE isn't the best for temps but I like it)
