I don’t have time to log in here often but this thread got brought back to my attention in my notifications.
real world results of a PRS shooter: 2 barrels of different manufacturers both lost ~30-35 FPS at 2500 rounds. Still shot as good or better than when it was new. That shooter added a few tenths of powder and won 2 one day PRS matches back to back weekend and dropped less than 5 points at both of them. The real kicker is that they are 25 Creedmoors running 3140 FPS with RL16! That’s smoking. May be why my 25x47 running my slow node at 2810fps is still the same every time I take it out with over 3k Rounds on the tube.
