Awesome info. Thank you so much guys. Long range,you pretty much answered my question perfectly.
I was considering criterion because I was up all night last night reading the aftermarket barrels forum. Got to page 20 before nodding off.
So if I'm reading you right you're saying bartlein and krieger are on par with each other so far and the shilen were great but required more cleaning vs the other 2.
I can source shilen barrels from my supplier however I think he can order bartlein.
So are we saying forget these new profiles and run with cut rifling,or the fad actually has merit?

Thanks again for the great answers. You guys are great.
