To respond to the OP's question regarding Lee dies in the Dillon press: The Lees will work fine, and produce the same ammo as Dillon dies; however, Dillon dies are radiused a bit wider than most at the mouth of the die to allow easier use on a progressive press. Your turret only slides one round into one die at a time, so a little misalignment is easily corrected as the round starts in. On a progressive press four rounds slide into four dies at one time. Familiar with the engineering concept of tolerance stacking? One round is off a little this way, another that way, another a third way, and your press suddenly won't go until you manually free up the rounds.
Not a deal-killer by any means, and you'll find many who use other dies on a Dillon. But I use Dillon dies on my Dillon 550B for this reason.
Not really a valid point. I've used Dillon & RCBS dies w/ equal success. Others have used Hornady, Lee, Reddig, they all work if setup properly. The tolerances w/ most presses will not prevent swapping dies.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
