A couple of years ago for my 270W I worked up load with RL23 shooting Hornady ELD-X 145 gn. This was in a Sako, 1:10 twist True Flite barrel 24 inch barrel, Remington brass, Federal 210 Primer, COAL 88.00 mm ( 3.464 inches ). The RL23 charge was 57.00 gns. It gives MV a bit under 3100 fps.
It shot well out to 300 yds but beyond that was erratic suggesting to me bullet stability issues.
I no longer use this load however as I worked up another, much better, with AR2209 and the same bullet for around 2940 fps, that shoots really well out to 400 yds.
