Ran another 250 rounds of my own cast bullet through my G-36 and it ran perfectly. Can't say the same for my aging eyes but my 36 sure did its job. Have run cast bullet in it for ten+ years and that works out to 100-300 a week. Not a big deal for a Glock but my 1911's run just as well too. Got my G-36 after my wife complained that the 1911 was ruining her couch. She's a G-17 kind of woman so to keep the peace I got my first plastic gun. Use to be able to get better group with the G-36 than with thousand dollar Kimbers. Damn fine pistol in the hands of someone who can see.
