kneelingatlas Posted October 4, 2014 Share Posted October 4, 2014 My CZs will cycle with anything from an 8# to an 18#, there's a lot of room for experimentation in there. All I'm saying is that if you find yourself waiting for the front sight to return, a few pounds heavier might help. Link to comment Share on other sites More sharing options...
Akacala Posted October 4, 2014 Share Posted October 4, 2014 Kneelingatlas, what springs are you using with 147s? I'm about to start playing around with 160s in my cz, but I'm currently running an 11bls recoil spring. Link to comment Share on other sites More sharing options...
kneelingatlas Posted October 4, 2014 Share Posted October 4, 2014 11# sounds like a good place to start. When choosing a recoil spring here's what I do: fire two shots as fast as I can, if the second shot is high I go to a heavier recoil spring, if the second one is low, a lighter spring. Your load, gun, strength, technique will all effect this. Link to comment Share on other sites More sharing options...
kneelingatlas Posted October 4, 2014 Share Posted October 4, 2014 What do I have in mine? I lost track of spring weights a long time ago, now I just go by relative coil diameter... Maybe one of these days I'll make a spring tester and mark them. Link to comment Share on other sites More sharing options...
rtp Posted October 4, 2014 Share Posted October 4, 2014 Thing is, if you're looking for softer recoil, you're not going to go with a heavier recoil spring, as that'll require more powder to cycle the slide, and more powder = more recoil. You might if it's mismatched to your current load, and slamming into the slide stop...which I believe is Atlas' point.. Link to comment Share on other sites More sharing options...
