    Where can I find a good formula for breaking in a new 22/250 barrel? What about these specialized bullets for this purpose? Anyone with experience with these break in bullets? I believe Tubb's makes a version.

    There are several topics listed on here if you do a search that covers that...many times over.

    I shoot one shot and clean for the first 10 shots, then clean after every 5 shots for the next 40.

    Most barrel manufacturers have their own recommended break in process:

    Here's from Douglas Barrels, Inc ...

    CLEANING INSTRUCTIONS

    Run 2 or 3 wet patches with a good bore cleaner through the barrel. Then use a brass brush and wet patch again. When sighting in, clean every 10-15 shots. Always leave cleaner in bore when you are finished shooting. This will dissolve fouling left in barrel. The barrel should be thoroughly dried before shooting. If Sweets is used, do not leave in barrel more than 5 minutes. Do not mix Sweets with any other cleaner.

    Do not use stainless steel brushes or abrasive cleaners in barrel.

    fire one and clean for 20rnds. Then fire 3 and clean for another 10-15rnds. then fire 5 and clean for another 10-15rnds. It is now broken in.

    You will notice the amount of copper coming out on patches drops off drastically, and that is when you are getting close.
