*** How do you get the size of the images increased ???
My PM powered Crosman is a 1740
Crooked barn breech with extended probe.
Barrel is .177 10" with a nice crown, polished leade and ported.
Scope is a Walther 2 x 20. Grips are from Rick and East Indian Rosewood.
Trigger job, shims, lighter spring and adjuster with trigger shoe.
I've added a brass power adjuster for some bling and make it easy to remove the hammer spring.
I'm using a stock Crosman transfer port seal at the moment.
The UK Law is 6fpe for air pistols.
With a fill at 125 bar I getting around 22 shots at around 5.5fpe
I'm going to use some ideas from Robert's great posts to increase the shot count. Next job is to reduce the striker slightly.
