[QUOTE="Vol1975, post: 1701205, member: 100380"] Bullet interference. Sorry machinist talk. Other words it is Bullet case mouth pinch that the case has to bullet. A common term that is used is interference. Some people run .001 to .003 Ths. Most factory resizing dies run .001 ths but in today market u can put as much as you want on a bullet by what die you have. Most of my pinch is .002 with bullet runout less than .001ths. Depending on what die you use and whether the case is resized from the inside or outside their can be some difference with the oddball case thickness of brass. Hell I’ve seen when anealing brass and some are not anneled correct and the brass has a different bite on the bullet. Ever feel when u load a bullet that 8 out of 10 feel the same and then those two feel a lot different. Either easier or harder. Mark those and then watch the chrono. Lord OCD is taken hold. Hope this helps [/QUOTE]
