I own 3 . S&W Model 58 Ruger BlackHawk Ruger RedHawk (my daily carry now) Do you still want to know cylinder length's?I backed the crimp off and dropped the seater in the die to seat the bullet without a crimp. They all came out perfect. It’s definitely the crimp portion of the die.
On that note, who has a 41 magnum revolver still? I need to know what it is and how long the cylinder is. Unfortunately, I don’t feel all that comfortable seating the lino bullets deeper than 1.665” which is over max OAL. They are a tad too long for the Henry at that length. If they will work in a revolver, then I’ll go ahead and load them up. If not, I’ll set them aside for another purpose.
