Bob:
I also have Win 94 in .32ws, I shoot .323 sized cast in mine. I use gas checks but don't always need them. I don't have a mold at this time but did buy about 200
.323 gas checked flat nose 180gr(I think) bullets from Daniel at the Bull shop. You can search for links to his shop.
Although shipping from Alaska to S.A. may not be worth it.
My advice is to slug you bore or just shoot some sized and unsized to see which has better accuracy.
Glad to have you on the list, keep us updated with the rifle and post any pictures of game you get with it.
BTW I load up 10gr of Unique behind the cast bullet for a plinking round, lots of fun at 50 yards, recoil is like a .22
