Poop.

Have had a Rowan adjustable trigger on my .177 TX for a long time, when I fitted it I adjusted the pins so it matched the profile of the AA trigger I removed, and rifle fired as soon as safety was released.. wound out both until it no longer did this, and then adjusted the first stage screw, ended up with a nice tension on first stage and predictable let off on second stage

Just fitted same triggers to my .22 TX and Prosport, removed the trigger from the .177 and replicated settings on new triggers

.22 TX seems to have no first stage, .22 Prosport first stage feels vague and long, and both have a very light break on second stage

Is there a method for setting both stages? I've used the search function on here and found various threads, but if anyone has a tried and tested step by step method it would be greatly appreciated!
