I was reloading 357 magnum bullets using Titegroup and LSWC bullets. The recipe (2019 Hogdon reloading pg 155) called for 4.5 grains of TG and seating the bullet to 1.610. When I seated and tested the bullet, it was slightly longer than the case gauge. to get the bullet flush in the case gauge I reduced the COL to 1.600. That a difference of .010. Based on being at the starting load, I don't think there should be a problem.
I'll be testing the load on my GP100, but that won't be for a couple of weeks. Has anyone deviated slightly when seating 357 magnum ammunition. I looked up the max length in SAAMI and it listed it at 1.590 which is .010 shorter than the 1.600 I seated the bullet, but still the seating COL I used is .010 shorter than the COL listed in the Hogdon reloading 2019 edition.
I placed one completed bullet at 1.600 on my Ruger Security six and it cycled just fine.
Because I used the starting load and only reduced the COL by .010 from the recommended COL (which BTW is .020 greater than the SAAMI load), I don't foresee an issue.
Has anyone had a similar experience? If so, what was the outcome.
TIA
