[QUOTE="Bullet bumper, post: 682307, member: 17844"] I don't believe anyone advised "excessive neck trimming" You trim just enough to get them all square . Interesting however I don't get any " neck soot at all on any cartridge I load for " and if you are getting 1/8 of neck soot you are doing something wrong . However it has little to do with neck length in general and would have more to do with neck to wall clearance and neck hardness compared to neck tensions and chamber pressure . Internal donuts can also contribute . Your bullet is getting well out before the case neck can seal properly . Sometimes increasing the powder load will fix it. Some people have the bullet seated so shallow and only a light load of powder that this happens . Sometimes going to a slightly faster powder is better for the pressure , seating and neck tension conditions than the actual recommended powder . [/QUOTE]
