Thanks!John,
The 45-70 will run a 295gr. CEB Raptor and a 325gr CEB SOLID at around 2,500fps. That is as close to the 458 WM , as close as "damn" is to swearin'. (R7 or 4198)
The 45-90 is an easy re-chamber and has a more powder room. ( low cost chamber job.)
Or rechamber to 45-110. (Quigley down under)
The 45-70 will outperform the buffalo hunters sweetheart cartridge, the 450-400NE.
Most people can't believe this stuff because;
1. The steadfast concept that a 45-70 is lame old cowboy cartridge stops folks from thinking/testing/proving.
2. Very few people have experimented with modern unconventional bullets on cape buffalo and have seen how well they work. Most buffalo hunters are still using round nose bullets for solids on buffalo and they wonder why the bullet does not penetrate in a straight line.
The 450 NE 3 1/4 would be fine, just keep your pressure below about 40,000, I think.
I run very low pressures in my H&R single shot big bore. That is why VV N500 series powder and R17 powder is recommended. They have a bit "friendlier" pressure curve that some other powders.
Excellent .458 Solid bullets are CEB, NorthFork (from Sweden now), Peregrine BushMaster, GS Custom Solid Bullet. (I think that I missed some.)
Excellent expanding bullet is CEB Raptor, NorthFORK, Swift, and Barns Mono-metal.
The GSC expanding bullet has a good reputation in 375 and bigger.
Hopefully I am not being too preachy. I get excited talking about it. Brian
