6.5x54 with 140gr. at 2,700fps is really smoking for that round. What barrel length does Kynoch use?

That speed is right up with the best load for the 6.5 Creedmoor which makes it only with Hybrid100V powder and at 59,600psi, as well as the better data for a 24" .260 Rem at 57,000psi and 6.5x55 showing approx. 55,000psi, that's the 6.5x55's CIP max.

Even the 6.5/06 beats 2,700fps by only 100fps with all pressuresfor loads 2,730fps to 2,848fps, running over 61,300psi to 62,700psi - again, 24" bl.
A speer bullet was used in that testing.
I have to wonder if the barrel was at least 28" long for their test rifle.
