Now we are heading into new territory, but that is what conversations do. I have a perfect example of what RevGeo is talking about. I was at the range when someone accidentally put a .300 Savage cartridge into a M/N and fired it. He said he immediately felt the recoil difference. This was a factory Remington cartridge and probably loaded really low. I looked at it, and next to a case fired in a .300 Savage, there was no noticeable difference. The distance (By eye) from the shoulder to the base on both the .300 and M/N are very close, but the body diameters are way different. I suspect if the .300 Savage had been loaded hot, the brass would have really expanded and the results would have been much different. Backing off on loads DOES make a difference in brass life.
