I just got a brand new Redding Competition seating die for .308 from Sinclair this week. For the last few nights I've been trying to get it set up to be zeroed at 2.350" (to ogive) and I still can't get it. I'm using 175 SMK's so I thought this would be pretty easy. I followed the included instructions and it set up the die way too low and it was trying to seat the bullets way too far into the case. As in the ogive of the bullet was in the neck. So, I inserted my dummy 2.350" case and slowly unscrewed the die until the bullet and ram traveled all the way up. I then tightened the locknut and tried to zero the die out. I can get it zeroed using the adjustment screw, but within 1-2 rounds my seating depth begins to variate +-.01". I thought at first it may have been slack being taken out of the mic and it would settle out after the first 2 or 3 rounds, but it jumps around so much I can't get it dialed in. I tried adjusting the mic for each round individually to dial them in individually, but the results don't mimic my adjustments at all half the time. I'm debating returning this die and getting a Forster Ultra instead. Am I out of line to expect every round to come out within .001"? I also feel I should mention I'm using a Lee Challenger press. On Reddings website they mention a worn out press could cause inconsistent seating depths, but I feel my technique is pretty consistent and smooth and the press is only 3 years old. Anyone else have any experiences like this?
