Almost forgot - for comparison, the current [Ulrich] 40 Gr. BT, BC .290 (G1) works quite well via most 1:12" twist barrels, and is ideally suited to 1:11", which produces 1.5 Sg. I hope my weird sense of humor comes trhough- I'm not intending to be a wise-ass - just to support George's argument for mass. RG |

Randy, maybe if we switched to carbide balls they would have more mass..

I don't recall the weight/diameter, of the bearing I used in the thirty Cal. bullets, but the sectional density didn't/doesn't accommodate penetration. A .45 Cal. round-ball is about the bottom end for something the size of a deer - as I recall, .32 Cal. constitutes a squirrel gun. Remember, the jacketed tungsten-carbide [cored] bullets? Though, due to mass, they had fantastic BC, they lacked the precision for tournament shooting - even for High Power. The military messed with them extensively - and, may still use some. Bill Neimi used to tell the horror stories of the broken dies and PRESSES - yes, presses - when the tungsten-carbide cores were in vogue with Uncle Sugar. RG |

Yep still have some around here the cores make great tips for rest feet...

A better core material is D38, or Depleted Uranium. D38 is actually an alloy, 92 percent DU and 8 percent molybdenum.
The military has been using it as a penetrator for quite some time, we designed some impressive warheads where I used to work. Allen |

And there were also trials of an artillery projectile alloy made of ~90% tungsten with lesser amounts of copper and nickel. It was designed to be counterbalances for aircraft. One of the big commercial ammo producers experimented with both tungsten (not tungsten carbide) and molybdenum at one time. Both were way too expensive.
