i'm a firm believer that bullet placement is everything. granted, i dont advise 100gr bullets on elk, but staying within reason, a well placed shot is going to do the job. i dont use SMK's in my 270 because i dont plan on shooting more than 300-400yds, but on my long distance guns that i also do competition with, i use SMK's for accuracy reasons. shooting all summer long ensures come hunting season, i know right where that bullet is going to end up. one quick look around here and theres more than enough proof that SMK's work. so, if the bullet will do the job, and using that bullet year round i know how to put it where i want it, why would i use something else? that incorporates a whole new set of load data and requires quite a bit of practice time. i shoot the same load for competition right up until hunting season, and then use it for hunting.
If it were easy, I wouldn't be doing it.
