I recently purchased the Redding 223 Competition Bullet Seating die as a means of achieving more consistent Cartridge to Base to Ogive / Jump to Lands measurements for the three bullets I use on a regular basis - Sierra Match King, Berger VLD Target and Hornady V-Max.
While my standard Lee Precision bullet seating die was giving very good run-out results, I was having variances of 2-3 thousandths of an inch in my CBTO. However; with a bit of adjustment and a sorting of bullets afterwards, I am able to prepare uniform CBTO cartridges in batches of five.
I was hoping the more expensive Redding die would remove some of this CBTO variance and reduce the post-seating adjustment effort. To date, this has not been the case – the results are only marginally better.
At present, there appears to be just enough variation in the ogive measurement of some half of the match bullets to offset any increased accuracy of the fine Redding product.
Is the return on investment of the more expensive Redding die over the almost as good Lee die worthwhile? Not sure yet.
It may be the case that increased accuracy of the Redding die may be offset by the variations in the bullet ogives – the net result being only marginal net improvement after spending good money.
Is anyone else having similar experiences? Suggestions on improved technique?
