The old screw machine partitions have a relief cut in the middle of the bullet.You can't miss it. I will try to take a picture and post it. I buy them all the time in small lots in most calibers. They did that to reduce pressures as the partition was a hard bullet and raised pressures pretty badly....esp with the powders available at the time they came out. We don't know how lucky we are nowdays..even with the powders hard to find. Barnes is doing it with the X bullets now. That bullet really raised pressures so they started putting grooves round the bullet. I had some of the older 130 gr X bullets for the 30 cal I could get 3000 ft per second in the 300 Savage. I can get a little better velocities with the new bullets at safer pressures.
