To be honest I dont have a COAL I am shooting for. I just know that at 3.6 a 195 Berger is taking up powder space. I know I can make it work by having the barrel built to 3.6, however I was hoping to not lose powder room and keep the cartridge from looking silly. It seems likely that modifying the bolt stop and mag box would work, I was just hoping there was an aftermarket stock or extended mag that would solve my issue. Likely I will just have to Mcgyver it or have my gunsmith rack me up another bill. I trade computer work for gun work, so its not so bad if I have to go to the smith.
