Have owned a 6.506ai for a few years. Built on Sako75 action that started off life as 2506 and when bbl got shot out I decided to build something different hence the 6506ai. Started off trying to base loads on 2213 and RL19, then 2217 running 140 gn pills. Accuracy was excellent but speed was underwhelming (2750-2800 fps). More recently been playing around with RL25 and getting much better speed (2930-2950 fps) and good groups (0.6-0.7moa) running the old 140gn AMAX. With RL26 I’m guessing might do even better. Ballistically the 6506ai and 6.5-284 should be much of a much, as you see with 280ai & 284s. Pretty cool calibre, yanks reckon they can get over 3000fps. Recoil is mild as
