....edit to add Brent, most schuetzen shooters are using relative small bore rifles and exclusively smokeless powders, fast pistol type powders.

I'm not exactly sure what you are saying. But bp schuetzen is loaded without duplex, and typically involves drop tubing or compression or both and the calibers are generally larger than .32, with 38s being more common along with .40s and .45s (my personal favorite). Bullets are always heavy for bore. Again, air spaces between overpowder was and bullet exist without problem.
Are you thinking of BP silhouette, not schuetzen? The only schuetzen I am familiar with is the ASSRA sanctioned 100 and 200 yard matches where the groove diameter tops out at .321 with a rare occasional exception.
I was referring to the big fixed load long range rifles, as you mentioned possibly .375s, but more likely the .410s and .458s. It is not fun at all to breech seat using black powder. I havent done much of it, but the residue just forward of the case is a pain as it builds.
