I have a ULA Model 20 in 7x57. It is currently on route back to NULA because the bolt handle separated from the bolt, leaving a live round in the chamber. When I got home I managed to rotate the bolt with needle nose pliers to remove the cartridge.
The magazine is too short to function with some factory cartridges. Federal Premium and Privi Partizan will jam up in the magazine unless the bullets are seated deeper. Federal Classic cartridges function okay. When the rifle was new I asked Melvin for a cartridge OAL specification and was told "what ever length functions reliably". I once again requested a maximum cartridge OAL specification in the letter that I sent with the rifle for repair.
