Pure pewter boolits?

[45_Colt]

Constructing such a bullet with CG concentricity of the separate parts would be very difficult for anyone at home.

Tungsten is also very hard and able to be used as AP. If I remember right Speer in their 458 AGS used a tungsten core to get length of bullet down in the 458 Winchester. They did this because suitable powder selection becomes an issue to get full performance w/ an acceptable pressure curve. I remember that they needed to secure specific approval from BATFE. Also, I think 30 years ago these were several dollars apiece.

Such is one reason why match bullets are usually as simple and homogeneous as possible -- less tolerancing & variables to get wrong.

This is the whole point of my post. To elicit ideas of what can possibly be done. Doesn't do any good to just say 'no way', 'no how.'

Where there is a way, a need, folks overcome the obstacles.

As for match specs, ha, this is for hunting loads...
