Thread: My Shrunken Wood... need advice on No 4 Enfield.

One of the reasons .303's don't like 150 grain bullets is the throats are shot out from using Cordite the longer 180-215 grain bullets fit the throat better and have a longer bearing surface
to grab the oversizes grooves, first get the barrel slugged to find the groove diameter you could be wasting your time bedding it if the barrel is over .313" which a lot of them are.
