Loose fitting conicals

See, I ain't crazy!
I'd like to know why the T/C mold is undersize.

I'd say it's at least worth a call to T/C to find out.

As far as the .357 bullets in your .36, I wouldn't hold out a lot of hope. The rifling is cut with a slow twist to stablize a roundball. Fun to experiment, though, but expect to be disappointed.

The maxiball is undersize to allow east loading, the top bearing band is suppose to be the only one that engraves the grooves when loading...

In theory, the middle and rear bearing bands expand when fired and fill the grooves, thus sealing the bore...

To have a maxiball slide down and back out without effort is dangerous, the projectile can slide forwards and become a barrel obstruction without your knowledge...

That's just it. The top band does not engage.
Aside from loading loose, mine shoot surprisingly well, clover leafs at 50 yards.
Won't be a problem hunting as long as it's checked periodically to be sure it's seated.
I don't think they will just slide out of the bore but I haven't tried to make them yet.

No different than loading a mini-ball.

I would plaster on extra heaping of lube on the side bands to help hold it in place...

Or perhaps you could trim an over-shot card to fit your bore and use that tight against the top of the maxi to keep it snug against the powder...

I had that same mold that was loose in a Renegade, I just seated it hard with a solid brass ramrod, they never moved
after that.
re the .36, hollow base .38 wadcutters shoot very well, like small minis, but the fouling is terrible unless you clean between shots. Any .38s need to be pure lead.
