Ok guys I am a rookie when it comes to long guns and ammo, I have recently inherited a few guns and one was a H&K91 308, I would love to shoot it but I do not want to shoot ammo in it that I should not and screw it up. I have over the years read a horror story or two about bad ammo, corrosive etc. My question is with this gun what kind of ammo should i shoot and what kind of ammo should I stay away from. As I said I want to shoot it a little just do not want to cause damage to it now or down the road. I will keep the gun because of sentimental value but after I am gone you never no. I will just watch for replies. Thanks
