jc5,

Over the weekend I picked up what I take to be a BSA Lee Speed. Checkered sporter stock and express sights, horn or ebony foreend tip.

It is marked BSA and 311, with the second "1" overstruck to a "5". What do I have in the way of caliber, 8X50R or 8X57R? Or a .303 opened up to use .315 bullets? Bore is rough, but supposedly it is a shooter. Price was right.
