i played with .30 cal base band bullets a few years ago with mixed(mostly poor) results.i just got this one in the mail mot knowing it was this type.all driving bands are .375 and the base band is .381 and weight is 280g in a mix of 12 bhn alloy.its sorta odd in that the front bands are kinda groove diameter unlike others I played with that those bands were bore diameter. any ideas for getting type to shoot? it will be used in my badger barrel c sharps 38-55 hi wall.

Yeah I know the bottom base is were kind of rough I just cast a few after degreasing the mole just to get some Dimensions the sprue  plate needed some adjustment. 
I usually cut the sprue  with a leather glove so it's perfectly flat.
I knew somebody would comment about that when I posted the pictures I was right.!

I'll try softer for sure  but I typically had good luck with bullets in the 16 -1 /10 bhn range. 

Another question who makes a decent mechanical.breech seater for a high wall. The only ones I have are ones I've made up myself with a case and a handle.

I've had very good luck with bullets containing antimony but I was kind of "stuck"with 10,000 lb of linotype when my dad retired as a printer so that's what I had. The problem was his many times the bullets came out oversized for my Chambers. But some of my most accurate shooting with plain base bullets were with linotype. I haven't done a lot of work with breech seating though and I imagine antimony is probably something you wouldn't want in a bullet whem trying to force into the rifling manually.

Thanks for the info I'll give Russ Weber a jingle and have him make me a breech seater or two.
