Ok I got my rock river arms 458 socom upper last week I shot 3 rounds then the bolt locked up/ round stuck in the chamber. I have only tryed Corbon 300gr. Can't find any other ammo in fort Wayne. Is there anyone with a 458 socom AR that has had this problem. Or is there something I can try. If there is someone in fort Wayne that has some ammo other than Corbon that I can buy to try it would be very appreciated. Any help
Rock river said to clean the upper with a grinded down 12 gauge berrel brush. I tryed it but a no go.
