What is a good weight for a recoil spring in a CZ52? I use Winchester Tokarev ammo for my carry ammo and Romanian surplus for practice. the practice ammo is landing up to 30 feet to the right of me and up to 20 feet behind me, so I'm assuming my recoil spring is losing it.
I don't know where it stands with Winchester ammo since I only use that ammo at an indoor range since it won't put holes in the backstop like the Romanian loads (they are steel core).
I see some of you guys use 16 lb springs and factory is about 14 lb. I am going to order a replacement from Wolff today but some input before I order it would be nice.

Suggestions?
