[QUOTE="Rflamm250, post: 2131192, member: 105493"] I Know you have mentioned it in other post. But if you will enlighten me again. I have run an experiment with FL die vs bushing die. I consistently get better ES and groups with the Bushing die and Mandrel vs a FL size die with the guts out then mandrel. Both ending with the same amount of tension or whatever we are calling it say .002 under loader round. The only difference I can find is that the bushing die is not sizing the last little bit of neck, say where a doughnut may be forming. The bearing surface of my bullet does not enter the doughnut area of brass so one would think that sizing that part with a FL die would not effect it but best I can see is that it does. Am I figuring right? [/QUOTE]
