I just procured some Smith & Wesson Dry Lube and shot a little in a couple CZ-82 mags. I then cycled 50 rounds of S&B ammo through them and had no failures. I had previously fired 100 rounds of Wolf ammo and had a few FTF issues. I'm 99.9% sure it's the ammo and not the lube but wondered if anyone else has used dry-lube in any type of mag for their weapon and think it has done a good job.
