I also have a Remington 7400. However, I have had some issues with feeding. I tried different types of ammo to assess which might provide the best accuracy. That is when I started having feed failures. I read on one of the forums that the Remington ammo is specifically manufactured to cycle the 7400 bolt and that the 7400 is not as forgiving to other types of ammo. I also noted that the feeding/chambering process tends to dent lead-tipped ammo thus affecting aero-dynamics and subsequent accuracy of the bullet. All-in-all, I am still working on getting my Remington to perform up to it's name-sake's reputation.
