JFE hit it out of the park. You will not need a V thread receiver for a 356 Winchester. The larger bore diameter of the 356 produces less bolt thrust than the 30 calibers do and that’s the reason for sticky extraction problems with hot 307 loads in standard 336’s. I have a rebore 336 in 356 and a rechambered one in 307. No problems with either as long as you don’t hot rod your reloads.
