Hey i forgot, but when i was shooting that short barreled wolf, i noticed a lot less burnt powder on the snow in front of me. With my Optima, theres a good layer of BH209 on the snow in front of me. Another deal i noticed is how fast the Wolf cools down, even in 60* weather in full sun. By the time i looked through the scope, took note of the shot and then stood up and reloaded, that sucker was already cool to the touch. Maybe 2 minutes tops.
