The 26 is much harder to load for, much pickier in loads with narrower "nodes". It does drive a 140 a bit over 500fps faster, but some of the bullets like the bergers dont seem to hold together all that well past 3250-3300fps. They shot ok in my 26 just under 3200fps, but the 127lrx had better accuracy. I think the 26 is capable of pushing the bergers harder than what they like. The 26 will push that 127lrx to 3550ish, mine groups best around 3490, under 400 yards thats very flat shooting.
But my 6.5cm will push the 143eldx at 2805 very accurately, and out past 600 yards it carries more energy, speed and has less wind drift than the 127 from my 26. At hunting ranges there isnt much doubt that the 26 is just more than a cm, but long range plinking is all about high bc bullets and less about what you push them with.
