In my experience fouling is a non issue with the barnes crankin especially in a hunting situation.
Never put threw more than 40 odd in a session but fouling was no worse than amax or sst or interloc.
Maybe a different story if you like to cook steak on you barrel eh crankin
Tracers now they foul like nothing else,the hollow base allows 55-60k psi to push out copper against the bore. Fun If you like cleaning.
