Impulse Mountain Hunter 300 Winmag issue

Encountered an issue the first time I took my new rifle out to zero it in, and can’t for the life of me figure out what is going on. Pulled out a brand new box of hornady precision hunter rounds and it’ll either light strike half the rounds or it’ll fire and completely lock up. When it locks, the action will not move and I can’t eject the spent case. I have to resort to hitting the handle with a sand bag to get it to eject. Couldn’t even get through a whole box of ammo. Thinking I need to get in touch with Savage about it but wanted to see if anyone has encountered something like this and if there’s a fix I’m missing.
