[QUOTE="HARPERC, post: 1475069, member: 30671"] Learned a bunch from both these guys, and some of the conversation may be splitting hairs. At one time we had to choose: Speed whatever that means, vs Heavy whatever that means, stability whatever that means. It's kind of abstract until we start putting in actual numbers. I think there are enough cartridge combo's out there we can have both. At least in the range I'm willing to shoot at game. Once we do that a certain amount of preference comes into play, based on our experiences in the environments we were most familiar in, and what size game we intend harm to. SG 1.5 yep can make that work, 1800 fps minimum terminal velocity I can live with that, a bullet that survives in the upper end of whatever muzzle velocity we're working with OK. If I differ with Steve it's in the balance of velocity, and bullet weight. He will default to velocity, and I will go heavy. Using his 166 Sledge Hammer, and 84% weight retention yields about 139 grains to carry on when the petals fall away. Something like the Dead Blow 227 grain version retaining about 60% would leave about 136 grains. It would seem to me, generally the 91 grains of shed petals would yield a bigger wound channel than the 27 grains of the 166. This may be old school, but mass has made a difference in the bigger bones of bigger animals. Having not tested either for penetration I confess this is assumption. I think the flatter trajectory of lighter bullets will make up for some misjudging of distance, but in these days of laser range finders were not really guessing on the longer shots. [/QUOTE]
