Bismuth used in bullets what does grain

I get the feeling that many of these types of air bullets meet a sad end and fade away simply because they aren't spun fast enough to stabilize them properly. July 14, 2015, 04: This problem would be less with a lighter material, but would still have to be considered in the design....

With the Bismuth and Tin alloy being lighter than Lead, why can't that be used to make a high BC air rifle bullet pellet instead of making a high drag Diablo style pellet design.

Carbon steel melts somewhere between 2,600 and 2,800 degrees Fahrenheit, and the temperature needs to rise all the way up to 6,150 degrees Fahrenheit to melt tungsten. I understand what you are saying.... However, I've not heard of a pure Antimony bullet though. I really like the idea of an air rifle bullet like Bob's Boat tail, but his.

I suppose then you'd jsut end up with what the PileDriver is at that point. That twist rate, for subsonic stability with a flat base bullet, would be 5".... Or maybe Crosman and Prometheus could produce a very low drag air rifle "bullet" profile using the alloys that they've already come up with.

Maybe it could be a small lead core with a plastic outer shell.

Bismuth and Tin alloy pellets, or better yet air rifle bullets

At least it appears so. I'll try and do better.

I just think they used it on the wrong pellet profile design. That could be the ticket also. Why not modify your gun to shoot the heavier bullets? It s the most naturally diamagnetic element and has one of the lowest values of thermal conductivity among metals.

The physical problems to be overcome are the hardness of the material used, and the increase in length, of the boattail bullet.... I'm not talking about two projectiles that are the same shape or profile. Stuarts Draft VA.
