I bought the savage impulse predator in 308 recently and after mounting the optics I took it out to site in, but at best only 1 in 4 rounds went off. All of my ammo is technically 7.62x51, but that shouldn't matter. The ammo I am using never had any issues with my other rifles. Is there anything I can do, or do I need to send it back to Savage for them to fix it?
