260...you can make brass from 243 or 7-08's...and run 125-130's fast enough for Elk I'm told. No elk in east texas but some mega sized hogs get a dirt nap pretty easy down here from the bragin at the LGS's.
A guy I follow on another channel, next county over shoots a 260 T3 has just decided that NPT 100gr'ers are not reliable enough after several years. Has killed more of 'em than I would ever admit to without being accused of bragging, and recently switched to 120's after a butt high boar got back up and staggered off into the brush where no sane person would follow a wounded one, and kills lots of hogs all year long.
