I am just the opposite. I hunt with a fouled gun since my gun is much more consistent on a fouled barrel and I can only get one shot at POA with a clean barrel but many shots if needed at POA with a fouled barrel. I agree with bumping the powder charge up to 100-120 by volume. I shoot a 250 Barnes or TC easy glide with 115gr of BH 209 in my TC Pro Hunter and never swab between shots no matter how many shots I shoot at the range. My gun shoots better the more I shoot it and my last shot goes down as easy as the first.
