Off and on over the years, I have heard reference to bullets cast from Kirksite a zinc based alloy with a Bhn hardness of 100.

Today I was reading the September 1947 issue of The American Rifleman and it contained a long and detailed article by Robert Hutton about his work with cast Kirksite bullets. He used a Cramer 46 mold and fired the bullets in a 30-06. This mold will throw a bullet of 150 grains from a lead alloy, but the lighter Kirksite produced bullets of 110 grains. He was able to push these to 3,200 fps with good accuracy. He list lots of information and load data.

He was also able to push Kirksite bullets 3,800 fs in a 220 Swift, again with good accuracy.

It seemed to be the coming thing as Cramer was making a special pot and dippers for Kirksite use.

I Googled up Kirksite and it is still with us and used to make cast all kinds of things with high detail including molds and stamping dies.

If anybody would like a copy of this article, I will scan it and send it to you as jpeg files. PM me with your email addy.

If anyone is interested in Kirksite, I have several ingots. Probably about 100 pounds. Yes, it's HARD. PM me if you're interested. To guess shipping charges, I live in 85205. (Oh, yeah. There's also the USPS Priority Flat Rate box for up to 50 lb.)

Regards,

Stew

Bullshop... I had a rifle like that once, a new barrel cured the problem.

Realy 4200 fps with ACWW and 2MOA accuracy. 2 MOA is as good as that Ruger will shoot anything. I posted about this away back on Shooters and it sure ruffled some feathers but not a hair outa place here. This must be the brill cream crowd. Just no fun atol!
Let me give you a hint, 30/06 with a 55gn boolit pushed by 57.6 gn Re #7 for 4289 fps or 53.6gn IMR- 4198 for an even 4200 fps.
Got it yet?
