can 338-06 be made from 270 or will it be to thin or other probs. thanks jason

Standard case length for the .270 Winchester is 2.540 inches. The .30-06 (parent case of the .338-06) is 2.494 inches. .338-06 cases made from from .270 Winchester brass will require trimming after necking up. The danger is that the neck will intrude into the throat, and hold the bullet too tightly, causing breech pressures to spike.
