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. From a clean bore. Reason is fouling characteristicsfrom shot to shot varies and obviously increases as you shoot which creates more fouling.

To take a rifle from storage and prepare for hunting with sabot's.
I remove the rust protection lube from the bore with alcohol/windex and dry patches. Then run a natural lubed patch in the bore followed by a dry patch to control any flash rust(Idon't usethe dry patch after the natural lubed patchif shooting conical or PRB). Then load as desired with powder and projectile.
