Hi All, after some help. A mate has just bought a second hand M77 Hawkeye in .223 Rem. Took it to the range today to try it out with some Buffalo River ballistic tips. I told him to push them to the back of the internal magazine to prevent the tips being damaged. However, when loaded like this the bolt is failing to collect a round from the mag on its way through. It does however just catch one if the rounds are pushed to the front of the mag. It's a hunting rifle so needs to feed reliably.
Any ideas what's going on or does it need to go to a smith?
