[QUOTE="JPatzig, post: 2942213, member: 115466"] I've seen consistent feedback that Hammer bullets shoot better groups and have lower SD in speeds with "more" neck tension (typically .004"). Has anyone tested different neck tensions (.004, .003, .002, .001) and seen different results? Or have people generally seen that more is better across the board? I know I can just test for myself, but thought I ask before I buy mandrel sets and expend reloading supplies. For crimping, I've seen mixed messages on crimping the "peak" vs. the "valley" of the bands. I feel like crimping on the peak actually applies pressure/tension, where crimping into a valley wouldn't actually do much if anything. Am I wrong? [/QUOTE]
