So heres the deal. I just had the chamber recut/setback from a factory Remington 700 308 chamber to a tighter match grade chamber. With the new chamber being tighter, If I used the same load as before would you expect to see higher, lower or similar chamber pressures. Example. All my previous fireformed loaded cases will not chamber due to being too large for the new chamber. If I were to pull the bullets, resize and reload with the same amount of powder, what would the outcome be. Obviously I will have to work up a new load but I want to see if anyone knew what the new chamber pressures would be from the same loads as before.
