warbirdlover,
You're way behind the times. Barnes solved the fouling/accuracy problem when the introduced the Triple-Shock X-Bullet (usually called the TSX) in 2004. It has grooves around the shank of the bullet, which not only reduce fouling enormously, but allow it to shoot more accurately in most barrels.
But being a lifelong believer in Partitions also works. In fact, unless you hunt game bigger than deer--or deer at longer ranges than you typically shoot them in Wisconsin--I wouldn't bother switching.
