Why does a flat nose solid penetrate better than a round nose? Is wound channel difference a viable concern when talking about solids? I'm impressed by the visual. The .470 Nitro solids that were fired into the shoulder of an Asian Water Buffalo and found at a hunt a couple of season ago were badly bent and not nearly as uniform as these. I don't know what they were but penetration was poor... really no better than the heavy soft lead muzzleloaders we were shooting. If we want penetration from odd angles and use solids as a backup round to a soft point on buffalo which bullet do you recommend... a round nose or a flat nose?
