Speer round balls for muzzleloaders

I just discovered that you folks carry a few sizes of Speer round ball. Especially nice to find .350 for my .36 cal rifle. It appears I got the last of the .440 balls today.
I don't know if you're bringing anymore in, but I'd be in for some .530/.535 and .310/.311.

Yes, they should be restocked soon

Thanks.
