That's wierd that a remington rifle doesn't like the ammo that Remington makes for it. LOL! Thanks for the heads up. I just bought 3000 rounds of Federal HP copper plated so I hope I'm safe.
Remington makes 30 round mags for the 597 now!
I tried one of the 30 round mags, and had nothing but problems. It would cycle the first 3-4 rounds good then jam. Fire a round then jab. I wound up trading it back for a 10 round. I know some other companies make them, but not very many. The local shop sales them, I may give it one last chance.
