I almost hate to inflict that video on you… just another YouTube pontificator who doesn’t take the time to organize his presentation before talking. Here’s the deal: It’s not the gun, it’s the ammunition. Skip the talking and just go to the pictures.
ZSR ammunition is made in Turkey. I have some of it from an earlier lot. I’ve experienced no problems so far, but I doubt I’ll fire any more of it.
Check your stuff.
And keep improving your position!
