Re: 30 Cal. SMK\'s for Elk?
SMK's actually perform well under a wide variety of velocities. With SMK's though, is that a good rule to go by is the faster they go, the heavier they should be. That is of course in the hunting application. For elk, with your loads, I would use 190 MK or even the 180 if that is what my gun liked. I probably wouldnt feel as confident with a 150 but that is just me. I have a buddy who killed an elk at 430 yards with a 180 SMK at 3100 FPS at the muzzle. I killed a dall sheep at 763 with a 168 at 2661 and a caribou at 300 with the same. So, the moral is the bigger the game and the faster they are, the bigger the bullet, at least for hunting with MKs. But they do work very well. If anything, they blow up a little more if you are close, hence the more lead is better routine. I hope that helps
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
