I have found that my Inland was a lot more accurate at 200 yards than I thought it would be. Would I want to use it at that distance in combat? Only if I had no other choice. As stated it was intended as a personal defense weapon and not a main battle rifle. As far as lack of penetration goes I heard it was the thick quilted clothing and that's not to say it didn't penetrate but perchance it didn't penetrate far enough to do mortal damage. I was also told that when it got real cold some would take all the grease/oil out of there weapons and shave graphite from a pencil into the actions to solve the problem of freezing and or sluggishness of the grease/oil.
