[QUOTE="Mikecr, post: 609731, member: 1521"] BROWNT there can be reasons for your dilemma regardless of the die. -For one, whatever OAL comparator you're using probably doesn't contact the bullet nose at the same datum as the seater plug. With this, slight variances in ogive radius can change your comparison. Micrometer adjustments are useful to counter. -Another is the press itself(it's alignment, flex & tolerances) and your setting of it w/resp to the shellholder. I've never used a Forster. I've used Redding Competitions with a Harrell press. But my preference is Wilson inlines with micrometer tops. This, because it eliminates press errors. -Oversizing necks can increase seating force to a point where you get wedging with the seater plug. A definite source of trouble for consistency. Oversizing is anything beyond 3thou under cal(after springback). I don't seat to within a tolerance. I seat to an EXACT number -every round. I'm also fussy about loaded round runout off noses. Wilson seaters and rational sizing take care of the last two factors. I qualify ogive radius on my bullets to eliminate the first factor. [/QUOTE]
