No idea what BCA recommends as far as break in, but I figure I'll test it like it will be used for the most part. We have a local match, 300 yards, 5 , 10 shot strings, 5 minutes per string, with a 15 minute 'cool down , reload mags' period between strings. No time for cleaning, etc. So...I figure test it like it's going to be used to see if the barrel is worth running.
