[QUOTE="mark slavinski, post: 2993128, member: 106325"] Just got a Christensen Mesa in 300WM. I always do my own version of bbl break in which is very consistant to CA. I own three CA rifles which were all shooters right out of the box, no break in really needed. I started with a load, got it zeroed then cleaned. shot another load 3” at 100 and cleaned. Shot another different load , 3” then cleaned. Went through several bullets, powder, cleaning and everything shot about 3”…..after about 50 rds, I cleaned and was really frustrated and ready to send back to CA. i figured a had better send some factory rounds down range to make sure it wasn’t me Before I called them. Had a partial box of hornady superformance 150 GMX on hand so shot a group with them getting a 4” group at 100. Had some PPU 180 gn SP tried a group with them and got a 3” group. Have a buddy with some Hornady 180 sst superformance and got a 4” group with them. Now I am ready to send the rifle back. Cleaned it again then dwelled on it for a while. I now have about 60 rds down the bbl and thought I need to try some heavies so loaded up some 208 ELDM’s and got a 1/2” group. Had to be a fluke so shot another group and got 1/2”. Went back to 178 ELDX and got a 1/2” group! Tried three other bullets and everything is now shooting 1/2-3/4” groups! All of a sudden I have a rifle that shoots that I was ready to send back….never experienced anything like this, CA says it takes 50-60 rds to break in the bbl, this is the first time this has ever happened to me.
