I have 3 rifles with christensen barrels, and have personaly delt with 5, and know of 4 more localy. One was a wrapped factory sendero barrel (not mine), and after shooting and loading for it I would definatly avoid this as I saw almost no benifit for the $600 expence(ouch, might as well just give the money to some one who needs it). One of my rifles is in 300RUM, after rebedding it in a different stock it shoots 1/2 moa all day(usualy better). This rifle is super light and shoots as good as any custom I've ever seen. I have also delt with a 300WSM, this rifle aslo shoots extreemly well. One of my friends shoots a christensen 308 Warbird and it also shoots very well. Now for the not so good, I have one in 270WSM with the sporter contour, and one 7mm with a bull contour. both of these rifles shoot ok, but not what you would expect for the money. As for the other rifles i know of, they are having the same results. The 30 cals seem to all be shooters, but the others (22,6mm,25,270,7mm) all seem to be very finiky and not what you would expect for the money. As for my opinion, I personaly am stearing away from any more christesens(shilen). I feel ABS is a superior product all the way around, and am recomending them to who ever I know that wants a carbon wrapped barrel. I will be get'n rid of my 270 barrel and replacing it with a abs/satern barrel because I'm not happy with its performance. I sould how ever incude I have taken 4 animals over 500 yards and 2 over 600 , it typicaly keeps em in 4"@500yards(my 300rum keeps em in under 2" in good conditions when i do my part) . I have one friend who just purchased a Magnum Research blank in .224 bull 1 in 14 twist for a 22-250 project, I will let you know how it works out.
As for my opinion, I personaly will not use any more christensen barrels for a couple reasons.
1-only the 30 cals I have delt with shot well.
2-The customer service at christensen sucks, they sent my last barrel back with out the brake!
3-The one stock of thiers I used that they bedded had to be rebedded by my self.
I am a big fan of the carbon barrels, but would recomend using a ABS and a smith who was concerned with doing a quality job over high production.
