For those 357 Maxi owners......
I have ordered a MGM .357 max barrel. I need to send them a dummy round with my bullet of choice, 180gr Hornady SSP bullet, and instructions to how long the throat should be cut. So this is where I ask your advice. How long should it be? I have read a few articles online and learned, that in one man's case, 0.020" to the lands was a good "sweet spot" for his best accuracy. Since I have the choice and this bullet has a crimp groove, I would like to get it close. Good thing is, I can always have them take out more later, if needed.
Thanks, Dinny
