Last year I started using xlc bullets in my 300 rum and they worked well. But this year when I rechecked my zero I couldn't hold a pattern under 3 inches and it has wondering can the xlc coating be apart of the problem?(nothing else seems to be wrong, scope mounts, ect...)I have never had this problem with other bullets (coated or other wise) I started use xlc for the reduced pressure. Any help will be appreciated.

If you have any ammo other than the XLC that you shot last year I would shoot it this year to see if it is also shooting larger groups.

What do you use to clean the bore?It is possible that the barrel is fouled badly.Personally,I much prefer the tsx over the xlc.

I found fouling to be a problem with my rifle and have gone to the TSX bullet . Barnes just put out a new CD on the TSX that is interesting . www.barnesbullets.com
