So I just bought a m77 m2 target 22-250 I have wanted for a few years. I bought the gun from a young man that said about every 4th case wouldn't eject. I went to buy Hornady ammo and it's all sold out. I bought some Winchester 55gr soft points. (ALL I COULD FIND) I found about the 4th round the bolt went down hard. Then it would not pull case back very far. About every 3rd she'll is having bolt locking issues. Where do I start? It's also a tack driver!
