My wyf's self defense load in her 36-1

Thanks Dan, I haven't worked with (known) 30:1 alloy.

I've still got some of those Hornadys left over from when my late father was bulk buying in the days of cheap shipping a long time ago.

Just don't use them with your muffler!

The .30-40 Krag was built around a 220 gr RN bullet. It has a long neck, ~0.485", and really loves cast bullets.

My Contender Carbine has a 1:10" twist, .308" bore and really likes 180gr-200gr cast bullets (20:1?) @ 1,500-1,900fps. One issue with using some of the older .308 caliber cast bullets in most "modern" .30 caliber guns is the greater number of grease grooves, causing them to seat the bullet way down, past the neck and into the powder space.

Your cartridge's long neck should grip that bullet perfectly. I have a .30 Reece case sitting in front of me now. I met Mr. Reece at the Wanamacher's Gun Show in Tulsa a few year ago and we talked a bit about this type of cartridge and it's potential.
He collaborates with MGM to make barrels for his creations.

I can't wait to see the results!

No, won't be doing that.

A couple of pics for Mathman of soft bullets and what they do.

This is a CB short bullet, BHN of 8 recovered from the neck of a largish hog after it penetrated fully thru the skull and brain. MV ~710 fps



The skull:



A 300 grain pure lead paper patched .44 Mag bullet of pure lead, 1600 fps at the muzzle. 1.5 caliber ogive radius with a very minor flat on the nose of 1/8th" or there abouts. I don't have a pic of the bullet unmolested. BHN 5. Hit a deer at ~75 yards, broke both forelegs, 5 ribs and cut the heart in half near the top. Retained weight is 297 grains.



I have another of similar form that did a hog of about 125#, high on the right shoulder found under the hide in the back of the left ham. Bone carnage included shoulder bones, ribs, vertebrae, the hip and socket of the left ham bone. Retained weight was about 285 grains, impact at about 15 yards.

The 30:1 alloy runs about the same hardness as the CB short bullet above and this particular bullet will have a BC of about .300 on average over the flight of the bullet to 100 yards. In this affair placement trumps other considerations to a very large degree. It will expand at the higher end of the velocity envelope.
