Had a light punch list today so I got home waaaaay early.

Boredom set in so I did a quick test with a cz 452 and a dip xp firing vs a factory. I've been wanting to test this for some time but pretty much fuggotaboutit. I did this in my dungeon range where I have a bullet trap setup for air rifle when its too freaking cold to go out for the bigger stuff.

Ammo used was cci quiet segmented. I only touched off 5 each for a total of 10 as they kinda stink up the place. I am not setup to properly vent.

Original factory fp spring.

Dip xp fp spring

Bear in mind this was only 5 shots so I would certainly expect to see sd's climb with a more thorough shot regimen.
I'm going to do some more testing with both springs this weekend outdo with different ammo, however looks like there is a pattern arriving such as expected.
