[QUOTE="lhsmith, post: 1298974, member: 100947"] C.S.- You, apparently, have good results with them. In Benchrest Sanctioned match competition, one has to fire rounds as rapidly as possible in order to get all 5 record rounds on the target in one condition (i.e. same wind direction/ velocity, same light condition- same mirage). This is with manual feeding one cartridge at a time as per rule. ANY interference in chambering will cause the rifle to upset in the sandbags-causing the rifle not to track the same way each time- taking precious time to retain previous point of aim. I know of no one in this game that uses these dies for this reason. Benchresters transitioned from neck sizing to full length sizing over a decade ago when accuracy gunsmiths started specing resize reamers that very closely matched the chambering reamer. I have used a forster bump neck die and confirmed they do indeed change the case diameter at the body-shoulder junction. If I remember correctly from your posts on Accurate Shooter, most of your experience lies in military rifles. I am not limited to starting to mid pressure loads. To be competitive I have to load in the upper load tier. So neck sizing is not an option. Obviously results will vary depending on your chamber dimensions and die tolerances and end use. [/QUOTE]
