I have 2 rifles that I switch barrels with, one was originally a 30-06 and the other a 7mm mag. I can use one or the other bolt easily enough when I swap in my extra barrels, but I am wanting to get a hold of another standard (30-06 case) magazine. And, are the blind mags easily removed/replaced? Also, would it be best to have a short magazine for cartridges based off of the 308 or do people find that these work fine in the long magazine.

I typically only shoot single shot, but this year I hunted with a 30-06 in the magnum setup and could only reliably load one in the chamber and one in the mag.
