Default Any issues reloading these headstamp 9mm??

I was just wondering if anyone here has had any issues reloading brass with the headstamp WMR and/or WCC. I have about 5-600 of the WMA and 2-300 of the WCC that are ready to go but I don’t know anything about them. They have the + so is there any difference in the brass that would be an issue. I use a Dillon XL650 all Dillon brand dies.
Thanks for any information

The WCC brass is NATO. The "+" is a NATO cross, not a plus.

The brass will be crimped, so it will be more difficult to deprime. You may need a primer pocket tool to get new primers in without undue effort/crush/offset risk due to the wings/flanges created by the crimp.

NATO brass like WCC is also generally thicker walled and generally more 'stiff'. You'll feel it in the resizing process and may want to use case lube even if you're using carbide dies. It tends to get stuck on the expander die for me.

You may need to adjust your crimp die slightly as the thicker wall will crimp more, pushing the case to the same depth in the die. Similarly, belling the case mouth may require some adjustments.

It's more work to reload that brass, but it's not a safety hazard. The other thing to keep in mind is that because it's thicker, they tend to not like lower power loads. If you do, the case may not expand properly on firing and you'll get gas pass the case mouth and into the walls of the chamber. This can lead to build up and failures/erosion over time.

Exercise more care with your loads using this brass with lead, plated or otherwise oversized projectiles in pistol calibers.

It's safe, but understand it is different and how the differences will affect your cartridges.

Thank you for the information! I use HP-38 powder and load 4.7-4.8gn with plated 115 bullets and OAL of 1.140. In your opinion,Does that sound reasonable for the WCC brass?

Bullet shape has an effect on how far into the case the base goes, at a given weight. Don't assume a given OAL should be the same between projectiles of the same weight.

Look up your recipe in one or more books/data sheets and see if you're in the upper end of the range.

Worst case, it's under charged and you'll see carbon/gas marks pass the case mouth down the outside wall. That likely indicates an underpressure condition. However, don't attempt to increase the charge beyond maximum trying to chase away this symptom.

If you have a chronograph, you may see a minor increase in velocity with the brass, due to less case volume, and changes in crimp/neck tension.

With plated, it's a lot easier to overcrimp with this brass and cut through the plating, or not expand the case mouth enough and shave plating with the mouth edges.

Do a few installs and pulls of no charge, no primer loads and make sure your plating and crimp are OK.

Thanks for the info. Iíll put it to use with dummyís first and when I have a good OAL and crimp Iíll load up 2-3 ladders of 5 and test out Sunday. Unfortunately I donít have or access to a chronograph so it will be strictly a ďfeelĒ thing for me.
Thanks again for you input.
