@Tailhunter ............... I don't like Cast Bullets to be honest. Back in my early hunting days especially with 45/70, there just was not much available then. Cast bullets was a big part of my inventory and I used them in the field quite a bit. If they were slightly soft, then the nose would deform, limiting straight line penetration. To hard, and the meplat would shear off. Hit bone, the meplat would shear as well. If treated as a "Soft" or expanding, then in that capacity they were ok. But if you thought for a second to treat them as a solid, or depend on deep penetration, or expect to crunch and munch bone material, then you would run into issues. I had one glance off the shoulder of a cape buffalo once, and damn near caused a problem.
We did a lot of cast bullet tests over the years, and in every single case, they came up short on performance. Good Enough? Probably yes in most cases, but given a choice, I would for sure go with the better bullet these days........
A few years ago I had a guy that was determined to hunt Cape Buffalo with a Marlin Guide Gun. After much pondering on what he should use, I finally suggested he use the CEB 400 gr Solids we had designed for 45/70. I actually loaded the ammo for him. I had the load running at 1850 fps. He was very successful in his hunt. At or around 35 yards he fired one round through the heart, buffalo runs 25 yards and piles up stone cold. Bullet exited far side of course and was not recovered.
For this sort of work for all the lever guns, I would only go with this type Solid. While I did use a Raptor in my 50 B&M Alaskan as first shot, I followed up with all solids after that. If I were to do that again, I would forget the Raptor, and go with all solids for any dangerous game, and would probably do so on the big bears as well..........
