The gun shop where I bought this venerable rifle said it was a military training rifle from the 1920's or 1930's, but I read that several thousand
of these were bought by the military in 1942 and 1943.
Anyway, I bought it mainly because of the nice Lyman front sight and the Lyman? adjustable rear sight, but sighting it in, I've discovered that with standard velocity ammunition you have to get 100 yards from the target before the very lowest adjustment on the rear sight will put the bullet on target. Standard velocity ammo shoots 3 1/2 inches high at 50 yards. I can shoot CB caps at 50 yards and the rear sight adjusts nicely to accommodate that. I had been hoping to be able to shoot not only subsonic but also regular long rifle standard velocity and high velocity ammo. My groups with CB caps are noticably less tight, and I'm wondering if CB caps are inherently less accurate at that range, or is my shooting just deteriorating today?
Closer examination showed the front sight is not original, and it has been peened very roughly in place, so here's why it is shooting high - the sight's too low. My first question is, did this model originally come with a Lyman front sight? What was the original sight like? Would I expect to be able to find an original front sight as a replacement?
Could a gunsmith shim or otherwise raise the existing front sight?
My shooting ability or lack thereof aside, with a barrel in good shape, benchresting this model, how tight a group should be expected at 50 yards?
