That arguement is brought up quite often; though I know that the Enfield/Ishapore magazines were not desinged to be used as magazines are in modern firearms, after inspecting the rifle and magazine of my rifle I see little possibly for any damage to the magazine if used repeatedly as a detachable magazine. There are no contact points between the feed lips and the rifle when inserting and removing the magazine. I also hear quite often the the Ishapore magazines are difficult to insert and remove, this is not true (for my rifle at least) at all; I can quite simply depress the mag release 'button' and the magazine quite easily falls straight out. Loading the magazine into the rifle is quite similar to that of an M1A, if not easier.
I am not saying you are wrong, just that I see no possibility of damaging the magazine in doing this, and if it turns out that the magazine or a certain part of the rifle is damaged, I can spend a few bucks (really inexpensive parts) and fix what I damaged. I would very much like to have a scope on the rifle, especially for deer hunting, but this being my only rifle, it will also serve as a rifle for emergencies, disasters and such; for such a rifle loading rounds one at a time will not due.
Perhaps I could customize the mount myself and offset the scope so that I can use stripper clips, it sure would be faster, cheaper and more effecient.
