My previous barrel was a 22" Broughton. I shot 48.0 in it at 2750. Verified by Ohler 35 and actual come ups. Heck, I managed a couple top 15 finishes in PRS matches with it.

When it came time for rebarrel (4500 rounds), I wanted to get 2800 or better. Plumbed up this Rock 5R at 26" and it hasn't disappointed. Verified by Magneto Speed and actual come ups.
