Problem solved: main spring replacement made easy !

[Rickybill]

See if you think new Wolff #38 spring might help my problem. My concern is spring too weak, too much recoil and wear and tear on Toggle and Mech? Slamming it back etc. Shooting Fiocchi 7.65s and by all accounts too weak so maybe weaker spring is good idea.

I'm using the action spring that was in my .30 when my dad got it some time in '60s.

If I load 85gr bullets at less than 1100fps, the gun short-strokes.
If I load at 1150, function is perfect, but there are signs of wear on the rear of the frame, the toggles, the toggle camming surfaces on the frame "ears", etc., that might appear excessive after fewer than 1000 rounds; can the line between too weak and too powerful be so slight?

I've installed the Wolff striker spring in my gun, but haven't messed with the action spring, as long as the gun is running.
