I have been going nuts trying to find some sort of accurate information on load data for this load. Really a couple of loads, but mainly the 358429 Keith bullet in a Ruger GP-100 357 magnum. I have found a decent load using CFE Pistol for 158 grain loads but nothing for the 168 grain load. Also is the COL, They call for 1.590 if I remember correctly and that puts the entire bullet in the case and I will be crimping above the top driving band. Now, although I am only using about 5.3 grains of powder I am also thinking this could be a pressure situation. Now I did see an older post on another forum, don't know which one, it was a search. The poster said he never has never paid attention to the internet data since he started loading revolver bullets in the 60's. He simply crimps on the crimp groove and calls it good. Somehow that makes a lot of sense.
Next issue I have is wadcutters. I know they are loaded flush with the face of the case but again, no data at all for 357. I have a ton of 158 gr. wadcutters and I know I have seen somewhere that they shoot quite well from 357 mag revolvers. But no data. If I crimp at the face of the bullet can it recess into the case since the crimp is not holding it from sliding back?
