Thanks GWH, I've ordered the 140's as that's the weight mine is sighted for, I was reading if I want to use heavier projectiles I can use the adjusting screw on the front sight adjusting it lower . Would you know if this is the case ? Also have you adjusted the rear sight by drifting for windage ? If so what soft metal did you use for the drift , I was thinking of copper so as to not mark the steel .
Cheers.
