Wow, I don't understand how this works at all then...I would think a SA mag action would be the best fit for a SA cartridge. Why would a LA action be better?
I would think the long action chamber would be too long for a WSM cartridge. doesn't that leave a lot of play of the bolt behind the rear of the cartridge, or do you put a stop in at the appropriate length?
Also, doesn't that defeat one of the advantages of a short action, that being a shorter bolt throw?
Thanks for your advice!
