So I just bought an N frame S&W 25-8 and I’m looking to buy a mold for it so obviously I turned to my readings in From Ingot to Target where the author talks extensively about the 172 Keith SWC in the 357. So I looked it up on NOE’s sight and from the crimp groove to the top of the boolit is .360”. Well in my cylinder that’s just a tad long. So I took a factory round and using my boolit puller I knocked it out to stick out .3605” from the casing and it’s iffy on cycling. Takes a bit of jiggling to get it to lock into place barely.
My question is would I be able to seat it just a hair deeper and still crimp inside the crimp groove or should I just face the music and just get a 158grn SWC mood that will fit easier?
