Hi guys, I have been reading the posts for a while and am impressed with the knowlege of the membership. I have already learned quite a bit. I am keen to have some opinions on afew things. A few months ago I aquired an old Rigby .470. Serial # 18xxx, so it seems to have been built in the 1920s. All matching #'s. I get emotional just looking at it! For my first time at the range I ordered a box of regulating ammo from a guy who advertises in SCI. He gives you 20 rounds, 5 different loads, 4 of each load (make sense?)to see what your rifle shoots best. My rifle would not close with about half of the ammo. The top lever would not swing all the way to the closed position. (But understand that when empty or with snap caps in it, it closes very very crisply.) The brass that he sent me was stamped "Rigby". So I now purchased a box of Federal ammo. The rifle will close with that ammo but not as crisply as when empty. Is this a common problem? Anyone else have the same experience? I will start reloading soon and hope that I can fix this myself. Next question is about sighting in. Should I do this at 50yds, 100yds? I started at 50, however the express sight is marked 100yds. Does this mean that they regulated it at 100? OK my fingers are tired now, must stop typing. All your responses are appreciated. Thanks
