Tapered Boolit

[johnksr]

I have a 45-70 mold that casts a 247gr boolit that is tapered. It's .456 at the base and .450 at the top and are .620 tall.
Can anybody explain why it would be tapered?

I don't know why it is tapered but based on your dimensions, it seems way too small for a 45-70.

I have two of Lymans 'tapered' boolits for 40/65 and 45/70. It allows you to seat the boolit into the rifles throat to align everything before firing. Seated as shown you can load 77gns of FFG in the 45/70 and 70gns of FFG in the 40/65.

What he said!

When I got this mold I thought I would use it for squib loads in my .458WM, but after casting some and finding them a little undersized and tapered, I wasn't sure if they would be useful. Then I thought I could beagle the mold and bring the base up to a .459, but the top being only .453 would still be a problem.
The taper on this short boolit has me stumped, and disappointed.

My guess is that it is a boolit for one of the British revolver cartridges.

True, that would just rattle down the bore on any .45-70 I have ever owned.

I'm thinking even with the beagling, and the front of the boolit being undersized, it will just rattle down the barrel of my M77 too.

Maybe a muzzle loader bullet
