EGW Undersize Dies

Recommended Posts

For those of you using these, or who have used these, what's your assessment? I can understand the benefit of re-sizing cases ever so slightly under in order to aid the round in fitting into a chamber or case gauge. I'm just wondering if there are any concerns with that though, like: how does it affect accuracy, is there more potential for cast bullets (or any kind) to bulge, will I need to order custom, undersize bullets, etc.?

As always, I'm grateful for your input,

MM

I've been using them for over 2 years now for my 45ACP Major loads. Best thing since sliced bread. Previously, I had a lot of setback issues with mixed headstamp brass. I had to sort my brass to make sure certain headstamps were used just for matches. I tried Hornady, RCBS, and Dillon dies, all same results. With the EGW, no sorting by headstamps, no more setback. Life is much better.

Started with a hornady "custom grade" and had set back issues, couldn't figure out what was going on. Went to a lee U Die and never had another problem. I will say that junk brass like Tullammo still fails the case gauge almost everytime even with the U Die. The U die is the way to go!

I don't have any experience with the U die but I thought they can be a little more difficult to use on a progressive press (as they size the case down further than a typical die so they have a smaller opening) and you are working the brass more (not sure that matters to much as most brass is lost before it is overworked).

I worried at first also. However, I have loaded some of my 9MAJOR brass so many times I lost count. With good case lube there is little to no resistance while loading on a 650.

How about the progressive press issue, alignment is a little more critical with a U-die than a standard die correct? I suppose if you set-up your press and dies properly it isn't an issue but it is worth noting.

Take care in aligning dies and the press can run full throttle with no issue.

I consider buying one just to try it but haven't had any issues with my Redding Competition dies so I haven't bothered.

To summarize, the U-die sizes further down the case and sizes the brass between .002" and .003" below SAAMI specifications.
