I've had 3 of these AG42's over the years and they are absolutely a deadly shooter. Very easily the most acurate military surplus semi I ever fired. They do throw empties a LONG ways like so many others posted and that is absolutely normal. I have fired surplus Swedish ammo(likely Norma), Norma commercial stuff, PriviPartisan, Imperial and Rano ammo and the empties always end up a LONG ways away. I fired probably a couple thousand rounds through these rifles over the years and have yet to ever experience a jam or any malfunction of anykind for that matter. I can't say they were any less accurate than my tack driving Swedish short rifles either. I often wished I would have had a scope on an AG42 to see what it was really capable of. Very well made and accurate rifle. I never reloaded for the AG42 though so I can't speak in regards to powders and loads for that particular gun. If you're looking at buying one, rest assured they are good rifles!
