David, your comments hit home with me! I too had the sticky bolt syndrom in my original 6XC barrel,as well as two chambered with the original profile reamer. I had all three opened up with the Rev D profile last year but as yet haven’t had a chance to shoot ‘em to see if the problem’s been resolved. From what you post I’m not confident it has been.

I ruined several Win 22-250 cases early on with loads way too hot so stopped using those but the R/P always seemed to work well with more moderate loadings. If neck-turning works, that’s a chore for the (non-shooting) winter months around here.

Making 6XC brass from 22-250 cases pushes the shoulder back a bit while also opening up the neck. A 6-250AI ought to have slightly larger case capacity as a result of not only the shoulder being where it is but also from forming it to the AI angle.

There’s a drawing of the 6XC case here on the among the cartridge diagrams, if you have numbers to compare to what’s there.

Just a word of caution on Winchester brass, as many know, I was having major trouble with a factory Schneider chambered barrel and had major issues with sticky bolt lift even with mild loads. Even after rechambering with a little larger bodied and necked 6XC reamer I still had some problems with the bolt lift. This occurred with WW, Norma and Tubb brass. Well, after doing alot of experimenting I determined that the all of the above brass just had too thick of necks for my chamber unless I turned the necks. Norma worked pretty well but WW was drastic and really had to be turned. I started shooting Remington 22-250 brass and the problem totally went away. Norma also works well but occasionally I still get a little stick with Norma. I had this problem on 2 barrels that were reamed with the original spec. reamers, the other barrel that had the problem was a Pac-nor but not reamed by them. I can say that I tested the Remington brass very hot and had absolutely no problems. So if you have sticky bolt issues, try using Remington brass or turn your necks. Also, it didn’t matter whether I used moly or not. When I got the the 2850+ fps range, I had major bolt lift stick. Please don’t take this as a genrealized problem with the cartridge, I know of a few other rifles out there that have had this problem but very few considering the number of rifles that are chambered in the 6XC. It’s still a great round and just seems to be very accurate no matter what load I am shooting, Dave Fry
