they are a heavy max load that some firearms say do not use such as the judge ! i fired a couple of rounds and they were uncomfortable so i stopped and read that they are not recommended !Buffalo bore bullets website doesnt call them +P at this time
They call them "premium supercharged"
They are just loading them to real close to max book loads from my understanding--- lots of other factory 7rm ammo is downloaded.
Your semi auto may have issues with them, they may be too much gas pressure for the operating system. I would talk to B.B. first to see what their take on it is. Probably wont hurt the rifle, but it may not cycle correctly. Sometimes semi auto rifles need to use specific powders for proper operation.
