Savage mark ii/93....ejection issues?

the Savage mark 2 is an great gun an for the price it’s an excellent .22. Super accurate and fully upgraded already. The only issue is they have a weak ejector setup. The mark 2 doesn’t have a large aftermarket base or any way to upgrade so you need to keep it clean. .22 ammo is extremely dirty and it doesn’t take long for failures to begin. I use my mark 2 in .NRL22 match last week and began to see more frequent failures to eject and double feeds. The temps being below zero didn’t help neither! I tried different lubes but nothing would help. If you are having issues similar to mine, try a thorough cleaning of your bolt and ejectors. Thanks for watching
