Howdy,
I just tried out my new RCBS Matchmaster Seater die for 6.5 Creedmoor with Hornady brass and Sierra 130gr TGK bullets. I really like the features of this die, and the micrometer appears to be spot on.
Now, I'm seeing something that I'm unsure whether it should be concerning or not. My cases are fitting into my Hornady Cartridge Gauge just fine after resizing. I have had a few out of 20 rounds that I just made that no longer fit the gauge after seating the bullet with this new die. I tried giving them a little nudge in the gauge, which then scraped the case near the bottom of the shoulder.
First off, what would be causing this happen? Second, is this concerning? All of the rounds were easy to chamber in my Bergara B-14 HMR.
This would almost seem like the cases are growing in length after seating, or is it an issue with runout? I don't have a runout measuring tool, unfortunately.
