Lee Precision 90798, Universal Neck Expanding Die, 25 to .45 Caliber

This Lee die is a delightfully elegant piece of kit. By providing 2 stackable mandrels, Lee Precision covers the waterfront in neck diameters while letting you store both mandrels inside the die rather than have separate parts floating around. A couple reviewers have criticized the die for what they believe to be too steep of a flaring angle. They are missing the point. That's a benefit, not a flaw. It does require that you be more precise when setting the engagement depth of the flaring mandrel, and it helps to have your cases trimmed to the same length before flaring. But once you have it set up correctly this die allows you to flair just the last millimeter or two of the case mouth. Compare that to how flaring plugs work in typical pistol die sets. The plugs perform 2 functions rather than 1. First, the plug "uniforms" (read "widens") the upper third of the case you just sized and, only after that does it flare the mouth of the case. Unless you have a mangled case mouth that wasn't cured in the sizing cycle, this uniforming process just remove what little bullet tension you had after sizing the case. It also unnecessarily over-works the brass. By using this universal neck flaring tool instead of the sizing plug in your die set, you materially increase neck tension. This improves powder ignition, limits bullet setback in autoloaders and bullets walking out the cylinder in revolvers. This has become the tool I never knew I needed until discovering it 40 years into my reloading journey. Brilliant stuff. And I only need 1 die to improve ALL of my pistol caliber loads.

Worked great…

works perfect on 6.5 creedmoor. will try on 308. Expect same results.

Working great for my reloading needs.can’t beat the price.

So initially it is a Lee which I have always had great luck out of. However, I haven't gotten to use this one yet because it came in a box missing the small punch which is the one I need it for. So now I am trying to see if I can get it replaced from Lee. Which puts me behind on reloading. The item came in a envelope with the die free floating around. The die storage box was closed with the paperwork in it. I opened the box and low and behold no small punch. I don't know if this is common with Lee reloading items but this is the second time in a month on Amazon I have gotten Lee dies missing components. I am sensing a trend. I will update my review once I can use the item.Update: Lee customer service was fantastic, sent me the part that was missing and made sure I got it quick.

saves time

good Value

As expected, works great on my 347, 300BO and 556 cases. Great price too.
