Lady T,
I'll agee with you. Shortages may or may not happen. Rumor is most likely bunk, but best to buy sufficient reserves and be prepared just in case. In the event a shortage does happen you won't be crying later on.
I really hope it doesn't as I've just bought my first Mosin and have yet to shoot it. What I don't need is another caliber pushing $1 a round or more.
