Why not measure your chamber for the Max OAL for your particular bullet? The way I measure the Max OAL of a bullet choice is to close the action ,insert a cleaning rod down the bore until it bottoms out on the bolt, mark the rod. Open action and insert the bullet you want to load(bullet only not a cartridge) hold the bullet against the rifling with a pencil or something, re-insert the rod until it touches the bullet tip, mark rod again. the difference between the marks is your max OAL for that bullet. Note it can change with a different bullet weight/shape.
