[QUOTE="jstanton, post: 2405307, member: 102980"] I had been researching making the switch to mandrels for setting neck tension, but after watching one of F-Class John's videos about using gauge pins I decided to give those a try. In his video he was reviewing Porter Precision, he gave them a good review, so I ended up ordering some from them. I started with 0.262" gauge pins for my 6.5 Creedmoor and Lapua brass. So my question is that after I run the gauge pin in the case I noticed that it leaves vertical grooves, like a scratches or stretch marks maybe, on the inside of the neck. I checked the pin to make sure there were no burrs and it was smooth. I am using Imperial Application Media with Dry Neck Lube. Could I be using too much dry neck lube? I dip the case neck in the application media, tap the excess off, run the case up to the pin, let it sit for a few seconds, and then lower it back down. I also bought pins for my 7mm and 300WM but I am hesitant to try any more of these pins if I am damaging the brass. I used a toothpick to feel the inside of the case and they are definitely score marks in the brass. Any ideas? [/QUOTE]
