MILSURP Rifles
Concur with all the comments about the available ammunition; why buy what you can't shoot?
Regarding the Mosin Nagant, I seem to recall in my fuzzy old brain that the Russian Olympic team used them in the winter Olympics back in the sixties for the Winter Biathlon. That is the event where you ski cross country and stop to take target shots from time to time. In those days, the rules required a real .30 cal. or 7.62 rifle at long ranges. Now we just use .22 rifles at short range, which makes the site selection and preparation much simpler! As I recall, the Russians took the gold medal using the Mosin Nagant. If you like more material about this great rifle, see the film, "Enemy at the Gate". It is based on the true story of a Russian sniper during WWII. Very powerful stuff, and not recommended for the faint of heart.
