I made this statement in the presence of a client of mine, and I saw him give me a "you cant be serious" look. I smiled and tried to explain to him the superior vertues of the cast lead boolit, but I think the following picture had a bigger effect.
I have been studying feverishly for a year, trying to see how fast I can push an air cooled WW/pure lead alloy boolit with enough accuracy for hunting with. I was able to achieve sub MOA at 100 yards with my custom built 358 Win and a RCBS 35-200-FN going just proud of 2K FPS. (my goal is 2400, sub MOA but thats just to say I did it)
Anyway, an air cooled WW/pure boolit is pretty soft, and going 2050 fps makes for a pretty darn destructive combo. If anybody is thinking about shooting cast lead in your rifle, and wondering if the castlead boolt can hang with those new wiz-bang, HP, ballistic tipped, who's ya momma, new fangled jacketed bullets........
Ahem, I can say unreservedly, "they do" and at much less speed.
Observe the amazing damage inflicted on this small doe, 75 yards distant:

I actually was a little disappointed at the amount of destruction that the boolit caused. I believe I may harden my alloy just a smidgen so as to not ruin as much meat, but nevertheless this load will anchor anything I shoot with it.
The point is, that this is simply a 50/50 cast boolit that had a Hornady gas check on the base, lubed with FWFL. For a copper jacketed bullet to achieve this level of effectiveness, they have to be engineered very very well, and be pushed much much faster than 2000 fps. This is simply a more efficient answer all the way around.
