There are a few anectdotes out there, but mostly the fault of the bullet (winchester produced some horrible solids about 40 years ago)or caked powder and squib loads. My uncle used his in Mozambique and Angola in the late 60s early 70s on three safaris with good results and factory ammo. As most of you know, the 458 was just about the only big bore available during the 50s & 60s and it worked. Today however there are better choices out there, in my view the 450 Rigby, 450 Dakota and even the 460 Weatherby are all better choices. With thoe three, you can make them "cruise" at 2300-2400 fps with no pressure issues. jorge
No arguments there Jorge.
I just stumbled on a load fro my .460 shooting the 500 grain TSX just under .5" at 2500 fps. Need to replicate it of course, but it looks very interesting at the moment.
