Well, to be perfectly honest Savagefan, that particular No1Mk3 rifle seems to be extraordinarily accurate compared to my other L.E's, for some reason. I don't see anything out of the ordinary with it either other than it is relatively unworn in regards to all the metal. I can also shoot 2 to 3 inch groups at 100 yards, using the same .308 diameter bullet reloads with my iron sighted original, No1mk3's, No4's and one No5 Jungle carbine. That particularily accurate No1mk3 is the only full wood original Lee Enfield that I have ever fired WITH a scope mounted on it. Maybe they are capable of very good accuracy, just that the crude sights they came with don't do them justice. GRIN This one also has a very, very smooth and light trigger pull, although I see no evidence of any modifications being done to the thing at all. The fact remains that for about 20-25 years now I have been shooting .308 diameter bullets out of all my Lee Enfield's as well as my Mosin Nagants with no accuracy issues. I expect that they wouldn't do so good out of a worn bore however.
