I understand.

Interesting challenge the Herrett presents.

BTW: That .32 is a great cartridge in a small handgun {I LOVE the performance of ".30-.32" cal handguns for general woods wandering/small game shooting/trapping/dog shooting/butcher stock shooting}, but I can see why you wouldn't want such a thing in the T/C.

{My ".30" is the 7.62x25.}

You are locked into a really interesting project, probably working at the maximum performance level for the .30 Herrett; pigs. Maybe pushing it a little?

Back to the Partition; I am going to guess you could test it in your medium, then if you want a wee bit more reliable opening, trick the bullet tip a bit. I think easy job, problem solved. Whether it has the "Ummph" {technical term...

} to reliably anchor a large hog, not sure.
