When testing a new load I always start with a clean bore, I usually do not clean bore at the range, because I usually only shoot 10-15 shots, at a trip per rifle to be tested.
However if it makes you feel better about your loads take a cleaning rod to the range, and swab that sucker every 15-20 shots.
I don't get hung up on fouling anymore, since It never gets to degrading accuracy, because I don't shoot my rifles that much at one setting.
Thanks for coming!
