The Hornady 143 gr. ELD-X has, a thinner, Tapered, "Nose" and a nice, thick .037 "Shank" portion that helps this Bullet, Penetrate, "well",..
even at, 6.5 PRC Velocities.
I use, Forster Dies, so NO, nose, "deformation" But, I have been known to, "Lap" any, "problem Bullet's" to, my seat Stems, IF necessary.
After Trim, I chamfer Neck and "touch up" a Bit with, some Fine steel Wool. Then I use, a TINY Bit of case Lube on a Nylon Brush to clean and "Lubricate" Necks,.. LIGHTLY !
With, .002 / .003 Neck Tension, I have had, NO problems with, seating / denting any of, the High BC, VLD, type, or, ELD, Bullets.
