RE: Brown Bears and Muzzleloaders?
"...back in the early 70's Val Forgett took a .58 to Africa and shot all the big 5 with it. Can't recall the powder charge now, but I tried that load in mine...it was up to brown bear I believe. I'm sure if Val were still alive he'd agree."
Val used 180 grains of FFF and a 610 gran Mini..........never met the man, but I like his thinking!
