What was the load, Jim?

To me, it's most interesting how much more crisp the bullet grooves stayed with the harder bullet.

Wow! Those 30 bnh bullets dang near look like they're ready to load back back!

Velocity & accuracy were pretty close on the two different alloys. Everything else was the same, lube, diameter, gas check, primer, powder charge, brass, seating, crimp, etc.

If anybody has a Handi Rifle barrel in that caliber that they are looking to sell, please let me know.

I'm also willing to pay a fair price for hen's teeth. I'm figuring that my chances are probably better looking for the hen's teeth.;-)

What were the alloys?

[JIMinPHX]

The soft one was recovered bird shot + 1% tin, air cooled. The hard one was recovered bird shot + 15% babbitt, water dropped.

Excellent! I have a bunch of recovered birdshot; I will give it a try.
