40-65 mould

[Kurt]

OK, sorry I misunderstood.

You mean like this mould I had Paul Jones make?
I had him make this so I could seat the b ullet so the GG is at the transition filling the gap between the case mouth and the 45º transition the chamber had to eliminate the lead ring and so I don't have to use a cartridge seater to fully chamber the round.
It must have been a question also with the Sharps rifle company looking at the mould they made.

I would suggest when you order the mould adding the extra length on the base to keep the lube groove close to the base like the original Ideal Postell had or that sharps mould has. The base ring was the diameter like the band between the lube grooves to keep some of the bare lead off the bore.
