Now that’s sectional density!416 Rigby, Norma PH 450 gr, SD .371.
MauserDuff, Correct!And you can load the 45-70 even hotter in a lever action (42,000psi?). Buffalo Bore has a 380 gr. mono-metal solid at 2075 fps. And Grizzly has a 405 hard cast at 2050fps. Throw in some CEB slugs and you've got something.
You called it, I just added video.
As I said, my dog isn't in this fight, I'm not going to shoot a cape buff with any rifle at this stage. Just mentioning the .45-70 may be more powerful than some believe in a strong rifle. Not going to argue about DG using it.Yes the speed is there but the 400gr 458 bullet has a very poor .272 SD where as the 400gr .410 bullet has a very very good .340! This is why the 416 class cartridges penetrate so well…
