I have never ever intentionally fouled a bore to achive best POI accuracy or fouled a bore and then went hunting for the day.
I have always cleaned inbetween shots and recorded the best POI from a clean bore. That is the only way to abtain the best consistancy and grouping.
That is my exact thinking. You might get better groups after 2 shots in one rifle or 1 in another. But you never know what it will do a week from now or later. But I do know how a swabbed bore should shoot.
