Elmer wanted more velocity, even with swc's

While you were on ice, a new breed of jacketed hollowpoint came into general use. They work well at most normal velocities.

Some things have changed since the days of Elmer Keith.






 
Expansion is not always a matter of softness, but a matter of metalurgy and design.

You can actually make a bullet a tad harder and pre-stress, pre-frag it, so it has uniform, rapid expansion at a lower ballistic effort than older style bullets.

The pre-frag pattern in the jacket, computer designed and precision machine made, also is a significant factor, as is the jacket's bond to the core. The jacket helps peel the core back so it flowers.

Notice in the pictures shown the repetetive, almost perfect flowering pattern? You couldn't get that with simply an old fashioned softlead core.

The machinery required to make these bullets is very expensive and to reliably get these relatively uniform results, especially with homemade bullets, would be dicey at best.
