[QUOTE="Boe, post: 2258470, member: 25890"] I'm not arguing any of those points, I am well aware that. Obviously there is a difference as to why two lots bullets impact two distinct points of vertical impact throughout the course of fire. Course of fire being 773 yds to 1218 yds. This was confirmed when the marked rounds were fired in random order. The shot impact became very predictable with each lot . The test ammo was loaded on site from the same 10 pcs of sorted, prepped and neck turned Norma brass. Neck chamber clearance on the loaded round is .0032. .002 neck tension on the custom full lenghth size bushing dies. ES on the load is 3fps on a 10 shot string. The rifle, I chambered in 6.5-284 Norma with a Borden Receiver, 30" 1.250 Kreiger. Night force NXS 8-32 and weighs 19.7 lbs and very little recoil . The rifle was shot on a SEB front rest and Edgewood rear bag. Conditions were good. As you can see most of the variables were addressed as much as possible. A scientific test by no means. But, One might come to the conclusion that the only variant is the two different lots of projectiles. What is the exact difference? I don't know at this point. I don't really care, both lots group about the same. I am just curious as to why. But to assume nothing has changed since 2018 is a rather reckless assumption . Bullet dies eventually wear out and have to be replaced. I remember shooting BR in the 1990s. Custom Bullet maker and BR Shooter Allie Euber had a great set of dies that made the best 6mm Bench rest bullets ever at the time. When the dies wore out and and were replaced his bullets were not the same. They were still good but not as the previous set of dies. I'm sure some of you old BR guys probably remember this too. On another occasion I had a premium bullet makers lot of bullets vary as much as .003 to .018 on the base to ogive measurement. All in the same box. These are just two examples. It is a fact that there are more than one OAL of the 143gr. ELD-X. Where is the measured difference on the bullet profile? Base, Bearing surface, or forward of the bearing surface?
