I bought a 223 Redding die set to prep some new Winchester brass and it seem to take more force on the Lee classic press than I expected. I removed the expander to see if that was the problem and sized the case, without much change. Without the expander, the neck OD is sized to 0.236 and 0.245 with the expander. Does this sound like the neck is undersized? | ||

What is the neck-wall thickness of your brass? And, which case lube are you using? ________________________ "Every country has the government it deserves." - Joseph de Maistre | |||

I don't have a way to measure the neck wall thickness, but I'm using RCBS case lube 2. With the expander, a bullet seats fine with a firm hold. | |||

With the expander in place, the thinnest brass that can be accommodated is 0.012", so I would say that the dimensions are reasonable. If you know your brass thickness, then you can better determine what the die is doing. Redding can provide their design spec's. ________________________ "Every country has the government it deserves." - Joseph de Maistre | |||

Assuming you have a pair of calipers, you do, actually! Measure OD of the neck on a loaded round, subtract bullet diameter and divide by two => presto: neck wall thickness.

Good point! This results in a neck thickness of 0.011". | |||

As you have found, the expader/decapper has no effect on the difficulty of sizing. Nor does the thin brass of the necks require much sizing force. What's hard to size is the thicker brass from the middle to the head. It is likely that your chamber is on the large side and your die is likely on the small side of SAMMI specs. (That's common with small base dies.) Anyway, it means you have to reduce the thick brass a bit more than mormal. All you can do is insure that the lower half of the cases are well lubed and push on that lever. | |||

This new unfired brass, and this is not Redding small base die. Why would the die body squeeze the neck down to .236", then the expander opens it back up to .245". I know the dies are undersized to handle any brass likely to be used, but is there any brass out there only .006" thick? Does Redding have a service like Forster to open the neck to the customer's dimension? | |||

It is common for dies to size the neck down as much as .010" so the expander has to open it to the correct inside diameter. You can have your FLRS dies neck opened by Redding, most die makers will do this. You might want to look at the Redding FLRS Type-S Bushing die. This die lets you choose the correct bushing so your not over working the neck area. The die can be used with or without the expander button. | |||

The dies are made this way to accommodate a wide range of brass thickness. A bushing die avoids the overworking. ________________________ "Every country has the government it deserves." - Joseph de Maistre | |||
