[QUOTE="swampratt, post: 3268991, member: 15054"] The seating stem is much harder than the bullet is no worries on messing the stem up. Now some dies if you twist them in all the way to where they touch the case. Let me start over. Remove seating die from press. Place a case in the shell holder without a bullet. Raise the case up all the way towards the area where the die is supposed to be. Now twist the die in until it contacts the case. Stop. Now twist the die out away from the case 1 full turn. It could be your die is slightly crimping as you are seating the bullet. Lock the die in that position. Now adjust the seating stem so you get the correct OAL. That could be your issue and maybe not. Lee bullet seating die with NO crimp is different. Another issue could be the case mouth chamfer is too abrupt but I think i read that you are using a VLD chamfer on the case mouths. I have seen where the case is pinched .008" smaller than bullet diameter and the initial force needed to seat the bullet can be in the 150 psi area. .004" is the max I have went with good results. As in the case mouth is .004" smaller ID than the bullet OD. and .002" to .003" is better for me and my guns. So some questions for you . What case neck ID and what bullet OD.? VLD chamfer ? Is it a crimping die and bullet seat die in one? One more thing that can cause hard seating is rough case neck ID. One reason I brush all my case necks before seating. You can just take some sand paper and twist it into a cone and hand sand the seating stem. I use Fine bullet point cratex in my stems sometimes. [/QUOTE]
