Now that I've got two matched cylender bore chokes -

a) is this to low-rent for this board?

b) if not what do y'all recommend for bullets? (I'm building a mould).

I think that you will get lots of good advice. When people used such things in the British Empire the American type "Forster" slug wasn't well known. People use a projectile that looked liked a collar stud, or also the "Colindian" bullet which had holes through it (yes is true) in the belief that the air passing through would spin the slug!

Some of the Guns and Ammo annuals - I'm thinking 1970s - had good illustrations of these classic British projectiles. "Lethal Ball" "Contracta" etc., etc.

I think that the crimp is all wrong on the loaded round below...it should be roll crimped over the leading shoulder IMHO.







Several custom mold-makers in Australia and US carry this pattern. This one is from CBE (Cast Bullet Engineering).

I've seen pictures of Paradox rounds that were crimped just as the round pictured.

TRK: Might be fun to see if anyone makes rifled chokes that would fit your 10, essentially giving Paradox performance. I've had fun using the Paradox slug pictured in a 12-bore Pedersoli Kodiak percussion double.

It's hard to beat a plain round ball in a smoothbore. You can get some to try first at http://trackofthewolf.com
