My two brother in laws purchased their first guns last year an just about never used them. I keep telling them that they need to get more practise before the zombies showed up, but they haven't. I had them up to my back yard range and measured out 50 yards. I had my Mauser 98K and WASR 10 as well as the .22's. one brother in law brought his .308 enfield and the other his RPK. We were shooting from a picknick table which made a serviceable bench. The brother with the enfield just installed a 3-12 power scope, but once we got it close to zeroed, it was all over the place again. Turns out he didn't tighten the scope mounts enough.... back to step one. We got it pretty close (we didn't get it perfect since we will reset it at 100 yards in a few weeks.) but that took most of the day. My other brother in law did pretty well with his RPK, but he is not good with the basic functions of it, he had to be reminded to cycle a round into the chamber at the start of each mag, and it took him forever to change mags. I better get them in shape soon. On the plus side every time they pick up a weapon they checked the chamber to make sure it was empty, and every time they set it down they left the action open so I could see it was empty, so the most important lessons I taught them did stick.
