NOTE: If you plan to load above SAAMI max pressure and are concerned about primer-pocket leak, Peterson recommends you try the .243 Win SRP. While they do not suggest loading over SAAMI max pressures, Peterson's small primer pocket .243 Win have proven to hold up over SAAMI max pressures when tested in their universal receiver.
