Thanks for the clarification, however can you hunt with a 10 round lar in a 7615 since I cannot with the pistol. I don't think so but not sure. I can see it being OK for target shooting but would not the 7615 then be in the restricted class with the lar mag.
I don't believe there is a mag limit for manual action rifles (look at how many people hunt with enfields and 10 round mags).
