AHI, Thanks for the info, the R-P cases do feel very different when pushing the handle forward, much tighter and doesn't seat like the other cases. I will for sure try swageing some cases for sure and see if that makes the differenct. Thanks -Craig

Spokewrench: Did you ever find any solution to this? I have the SAME EXACT issue as you. 9mm, only R-P headstamps on XL-750. High primers, but just like .001 high, enough to cause lite strikes when used in my shield. I already have the updated Primer slide. I spoke with Dillon, Dillion said to adjust the timing, but the primer punch cup lines up perfectly with the shellplate, so I can't see how that is an issue Checked the height of the primer punch / cup and as per spec it's between 1.380 - 1.390 (Did this like 5 times already) Wondering if you came up with anything. Thanks
