Yeap the hk91 type guns puts nasty lines in brass. Soft brass that is. It's not reloadable. You can get Military Surplus ammo that has hard brass and it won't be tore up as bad but I doubt you can reload them. FALS have adjustable gas pressure so they can be reloadable. I don't know I think I'd rather have a armalite ar 10 carbine than a FAL. Right now a FN SCAR H in 308 is the best semi auto assualt rifle out there. Then I would say a ar10 carbine. The a FAL probably would be next. Last on my list would be the hk91 type guns. M1as are great but don't have the assualt rifle look to them and seem harder to feild strip than some others.
