[QUOTE="Litehiker, post: 1564290, member: 54178"] Interesting discussion. Here's an interesting one for you. When I was a Nordic Ski Patroller in the 1979 Pre-Olympics (and later the '80 Olympics) at Lake Placid, NY I patrolled the Biathalon events. I heard that only the Austrian and Russian rifles would shoot well in sub-zero temps and the morning began at -20 F. So we waited three hours until the temps got to -10 F. when it was deemed safe to ski. What did the Austrians know and the Russians discover from them about shooting .22 LR in sub zero temps? The Austrians discovered they needed a "swamped" barrel whose bore gradually tapered toward the muzzle a few thousands smaller than SAAMI specs. THAT was the "secret sauce" for .22 LR accuracy in extreme cold. HA! Too bad poor Remington didn't know that. They tried and finally gave up on building a good biathlon rifle for the American team. BTW, the last day of the Pre-Olympics was -40 F. at Lake Placid and -50 down in Keene Valley! All Nordic events were cancelled - after we Patrollers spent over an hour out on the trains in position for first aid evacuation with our specialized toboggans. Eric B. [/QUOTE]
