Note: Since managed recoil ammo has less powder , and thus less energy , leading to less recoil, then it may not operate and fully eject a spent shellin a semi-auto rifle.

Remington did not say anything about this when they intorduced the ammo, I bought some for my wifes 30.06 and it shot likea .223 or less, but the cases hung on ejection. I contacted Remington and spoke with their technical dept. They said they had not conducted tests with the ammo in a semi-auto,because they never really intended it for that purpose. A couple of months later I noticed that their ads in magazineshad notations that the ammo may notfully operate semi-auto action guns. So while it is great ammo, and semi-auto guns are nice, the 2 don't really go together. If you try it , fine, and if it does operate the action fully, great, but if it does not..... well , now you know why....
