Ive never had to swab with BH209 even in my tightest bores. Never needed a dedicated sabot solvent either.
Different barrels,different problems.What works for you might not work for others.What I suggested will cover most problems encountered. Each one singularly may or may not be a problem.. Some rifles shoot better with a fouled bore, some need clean. Some have rough enough bores that plastic from sabots build up just like cooper or lead fouling and regular solvents won't clean it. Some rifles of the same make and model will shoot well with a heavy load,some won't. Some rifles will shoot a particular bullet well and another of the same make and model won't. BH209 always shoots better when the bullet is seated with more force than say 77, Pyrodex or BP.
