Start with flash hole debburing and primer uniform and move from there. You could look at your necks and turn them or not. If you dont crimp the cannelure is not going to make a difference. The bullet entering into the bore as straight as possible is what makes the difference. And the powder getting an even light is what does it as well.
I would stick with the PH's myself. SMK's are designed to be match bullets and have filled a cross roll as a good-great 2 legged critter bullet. Still not convinced that this design is good for the 4 legged because it is not designed for that. That is why companies like Sierra and Berger ( one of the best in the industry) ) put disclaimers up that the SMK's are match bullets and not designed for hunting( not sure about Hornady. I know you can kill with them and people do but you can with a rock also and it is not the most suited projectile for it either.
