does anyone have load data for the .260 using 100 grain bullets? i have shot some of the hornady 129 gr. bullets @ about 2250 fps., and while accuracy is good, expansion [on the old 1 gal. milk jug] at 100 yds. is not impressive. i am thinking that the lighter bullet with more velocity would make this round viable for deer/antelope to around 250 yds. this is for a 15" barrel.
