Well....
Put the first pellet in my FAS 604 yesterday (not even zeroed yet), lined up on a 6yd target, straight through the 10 ring. Woo hoo thinks I - I'm going to enjoy this

Cock it for the second shot, pffht - burst an internal seal somewhere - no compression. Oh poo thinks I, got to work out how to take the flippin' thing apart now and fit a seal kit

Ah, the joys of old (ish) air pistols....
