I have a .357 Maximum rifle with a 22" barrel and 1:18.7" twist.
The 180gn cast bullets i have tried in the rifle have proven to be inaccurate and many people more experienced with this caliber are of the opinion that the twist is too slow for the heavy bullets.
The rifle shoots 1 hole clusters with 158gn Jacketed so that kind of proves their point.
So i'm looking for a mold around the 158gn weight but i have seen a couple of molds designed for powder coating where the lack of a lube groove means a 170gn PC bullet is the same cross section as a 158gn bullet with lube grooves.
So my question is.
Would the stability be the same with a heavier bullet that is the same length as a lighter one?
