Shorties For Forties

[nkbj]

From an adjustable length smooth sided mold a test batch of short ones sized .399 for the .401 bore Great Plains Rifle.
The length of paper ahead of the bore riding portion is there to scoop the wind and make instant confetti.
Will try these either over pressed paper discs stamped from egg cartons or else hard card wads.

May try them in the Green Mountain barrel too just fer grins.

Got my curiosity up..
I'm interested in a full range report when you have time.

Me, too. Paper patched bullets have always seemed a bit mysterious to me, but I understand they can be made to work extremely well.

They may be too light weight for the 16" twist GPR and too heavy for the 48" twist GM.
Basically this is an attempt to see just how light weight the GRP can be made to work without a hollow base.

My own limited experience says that the ballistic gods have a greater tolerance for light and short than they have for too long.

Looking forward to seeing the results

Oh yes indeed i am riding in the truck with you my friend. I am very interested in learning n making paper-patch bullets. I have an Under-Hammer .40 with a 1:24 twist.

smokepolehall,
If you come across an old Ideal / Lyman .44 caliber adjustable length "core mold", they throw a .39 diameter cylinder. That's what these are made with, with a replacement base plug to give the slugs a round-flat-point nose.

For a hollow base I'm using a .375 round ball mold given a cylindrical body, adjustable length with interchangable plain base and hollow base plugs.
