Put the 1377 hammer spring into the 2240 I have. Shots zip out LEAGUES more powerful. However accuracy greatly suffers and when being fed from the magazine it is a very stiff bolt. The stiff bolt is fine and easy to get used to but at 10 yards I'm lucky if I get a .75" CTC group. Then all of a sudden after 8+ magazines through the new spring the groups settled back to the normal one hole group at 10 yards. Is this normal or will they suddenly open up again?
No chrony data yet but I can visibly see more power from the gun. I shoot at a cardboard box with a bunch of paper in it so the pellets won't fly through it and before the pellet would just hit and be done. Now the box rocks backwards with each shot. Not a huge amount but enough to be noticeable at 10 yards when it wouldn't do that before. Going to pick up a chrony and a 14" barrel sometime next week.
