Im almost old. 45th season this year.So if the option is cup and core or not hunt at all, you’re hanging it up? That makes sense.
Speer used to make African solids with a chunk of carbide machined into the back of the bullet. The carbide was harder than lead but also really dense resulting in a much shorter bullet than most solids. Obviously the hardness would make it a poor thing to put into a bullet you want to expand
it's a good question. bismuth, tungsten, hevi-shot alloys are denser than lead. copper is a bit less dense than lead. I'm not ballistics person/expert but perhaps the denser than lead alloys would be too heavy for the desired ballistics compared to copper or regular lead. Again just not sure but suspect the ballistics are suboptimal, particularly for longer range shooting. I have no idea but also wonder about how "hard" those alloys are and if that is again suboptimal for performance on big game.
They love solids in Africa for their ability to break movers down into less agile less threatening movers. Moot for the discussion of killing game in the statesPenetration is far better (I am not talking long range), making them superior in that regard. That is why they love mono's for large game in Africa.
