I have been using my Wilson Ultra seater die for over ten years with zero issues. Tonight I am in the process of loading up a ladder test for a new Dasher BBL with a new lot of VT 103's. The issue is that about every other bullet sticks in the seater stem. I took the die apart and cleaned the seater stem out. It was very gucky (that is an actual industry term...look it up) so, I cleaned it out with break clean and q tips. Figured that my problems were solved , but..the very next bullet stuck in the die again. I am using a .266 bushing with no turn brass, so...way more than enough neck tension to hold the bullet in the case. I see no damage to the seater stem. Only thing I can think of is putting some light oil in the stem, but that doesn't fix the actual problem....something is wrong. It has to be the bullets, but I have no idea what it is. The seater has NEVER been apart and NEVER dropped or damaged. Any Idea's? Tod PS...tried a light coat of light oil inside the stem.... No joy!!
