I found the following tech update:

"On the WSM and UltraMag calibers, Savage changed to a controlled round feed bolt head in order to provide reliable feeding from the magazine. This bolt head differs from the rest by having the bottom lip cut away from the bolt face so that the cartridge rim can slide into the extractor instead of snapping over the extractor. Instead of a spring loaded ejector in the bolt face, this bolt head uses a standing ejector located at the rear of the receiver that pops up through a slot on the bottom left side of the bolt head to tip the case out. This is the only way to get the larger cases to feed from a magazine."

It references the Winchester Short Mag. Are there any issues with the 300 Win Mag and the older magazines such as from the 1997 timeframe? I am assuming those to be staggered?
