had an enjoyable couple of days in Birmingham taking in a concert and the Christmas market. Back home and getting some Christmassy stuff done. But found some time for a fiddle with the Crosman NP I bought and swapped about last weekend. Did the roller bearing trigger mod' and set up a scope. Okay, so far; the sealed ram gives it nice manners, but there's been a drop in output over this weekend compared to last weekend, when I bought it and tested it. Simple loss of pressure, or could the 10 degree drop in temp be affecting it?
