[QUOTE="Varmint Hunter, post: 2369485, member: 313"] While using a Lee FCD seems trendy with Hammer bullets; I've had mixed results with it. I originally tuned a few very accurate loads before I even considered crimping. Later, based on the many posts here, I bought several FCD dies and tried them out. Some loads had erratic velocity while others tightened up a bit. I think it's just something you've got to try on your own but crimping isn't necessarily "needed" with Hammer bullets. Some of the very light for caliber Hammers have VERY little bearing surface in the case neck. They would likely benefit the most from crimping. Some posters here crimp on the full diameter shank while others crimp in one of the parabolic grooves. It only makes sense to me to crimp in the grooves if you want the crimp to have the greatest effect. The last few loads I've worked up are crimped that way and have performed well at distance.
