Got my 12g testing rig all built (all of 5 minutes), loaded up a hopper, aired up the gun... Held the chrono over the barrel annnnddddd..... The chrono's battery is dead. Goddammit. Try again tomorrow.
For what it's worth, even dryfiring I couldn't get any kind of snow to come out of the barrel in 40 degree weather. That's more than I could say about any other gun I've ever used 12g's on. It is shooting low though, I'm 99.9% sure. With the Pipe back alone it should be much louder shooting at field speed, if my G1 is any indication. Of course that's got an L7 in it which have historically been louder than the L6's.
