Re: breaking in new barrel

Could be better I tightened up the Basix trigger to 10oz so ill be better prepared for the sear break tomorrow. Remember these groups were all out of a clean-shoot-clean-shoot barrel.

    How did you clean the barrel during your clean/shoot session?

    The routine is 10 shots -clean in between each. 5 groups of 3 clean in between each group. 5 groups of 5 clean in between each group. Using copper solvent each cleaning till no copper is seen .
    -or-
    Until no copper no copper is seen.


    My particular barrel stopped after 3 shots but I continued to clean and check for 10 rounds and I cleaned every 5th shot my 1st range trip just because in an ass .
    This was my best group on the 2nd range trip with different primer. (There are 2 speeds listed in notes I was comparing chronographs).

    Did that answer your question or was I rambling?

    Yes, but I still have another question. What did you use to clean your barrel in between shots? did you use patches and the solution or you used a brass brush and solution?

    the only reason I ask is because I have a new gun that I have been putting together but I have not fired it. I already got a jewel trigger, bedded the stock, installed a picatinny rail, and I just installed a scope. It is a rem sendero in 7mm. It should be a good gun, but I have never broken in a barrel.

    Answer is well appreciated.

    thank you

    I only use nylon brushes. Wrap a patch around it soaked in copper solvent of your choice ( I use hoppes benchrest but im sure there are better ones like montana extreme) run 2 or 3 down bore from chamber to muzzle only with a bore guide and use clean patch each pass till powder is gone that way you are sure the solvent is eating copper. Then l let it set for a few minutes and wipe solvent out with kroil soaked patch then dry with 2 passes with dry patches.
    I have a sendero sf2 in 7 rem mag and love it so much I rebarreled my xcr 338 win mag in 7 mag.
