I don't use them for everything, but on my precision ammo, it is the final step to set neck tension. It is also believed that any rough surface will be pushed to the outer side of the neck where some clearance is available and not interfere with the projectile as much.Would like to learn all about mandrels when to use them how to use them . Why they do for your brass etc Thanks to you all for your help. Teiy
Makes sense to meI don't use them for everything, but on my precision ammo, it is the final step to set neck tension. It is also believed that any rough surface will be pushed to the outer side of the neck where some clearance is available and not interfere with the projectile as much.
Is that a partition bullet in your avatar picture? Tell me the process of actually using a mandrel. Neck size only or not? Is a mandel used in conjunction with a die? That kind of information is what I need because I don't have a clue where to start? Is there a video that will be helpful. Thanks TribbThe expander ball in most sizing dies can stretch the neck and pull it off center when the die pulls it back up through the neck. Stretching the necks causes more neck length trimming too. A mandrel pretty much eliminates these issues. You will like mandrels once you start using them.
Remove the expander ball from your die, I always full-size but as minimally as possible, then order a die to hold your mandrel and a mandrel for the specific diameter needed size the case as normal and the last step for me is the mandrel.Is that a partition bullet in your avatar picture?

Thank you. Between you and can 1010 that explains it very well I'll see if I can't get into thisRemove the expander ball from your die, I always full-size but as minimally as possible, then order a die to hold your mandrel and a mandrel for the specific diameter needed size the case as normal and the last step for me is the mandrel.
I didn't think I'd use the .0005 mandrels but I bought some anyway. When you start adjusting neck tension and dealing with spring back, the .0005" adjustment comes in handy.I bought 21st Century. They have mandrel in.0005 increments.
