Hey guys, first post here. Enjoy the site, lots of good info to read up on and I have a question about the wolff magazine spring on my 930 spx that I just installed. In my search before this post I noticed 28" seems to be the number to trim the spring to so thats what I did. I loaded up a full mag of Winchester 2 3/4 hollow point slugs and it wouldn't load the first round. So I pulled out the shell stop and polished it up, helped slightly but still wasn't anywhere reliable loading. I kept trimming the spring down to 24 1/2" long, it seemed to be better but only 1 out of 5 hand cycles it would load the first round. So I pulled out another box of slugs I had that are Federal 2 3/4 slugs and they are a little over 1/16 of an inch shorter than the Winchesters I was trimming the spring to and over 7 rds that close to 1/2 of spring less thats its compressing compared to the Winchesters. It will hand cycle the Federals just fine as well as some Remington 00 that I have also. My question is should I keep trimming till I can get the winchesters to hand cycle reliably or just not use that ammo? I would like for this gun to run anything but I dont want to keep trimming the spring too much as I'm already shorter than what the other guys seem to run here. Thanks for any insight.
