I actually think the 419 press ability to lock down the turret is a great feature. Always bugged me when I saw my Lyman turret flex upward at the top of the stroke. I only loaded straight wall 45-70 on mine so I was not worried that much. But wouldnt a turret have to flex the same amount every time to get a consistent shoulder bump on a bottleneck cartridge? Just curious on what others think.
