Thread: 6.5 143 ELD-X, are they THE 6.5 hunting bullet?

I havent developed a load for either of these properly yet, but did do a speed ladder with the 18 inch one, got to 2630fps with a slightly compressed load of 2209 before seeing pressure signs. Going to revisit once im finished with working on loads for other rifles.

Ok so that being the case. I would argue that better performance can be achieved with a 129gn projectile vs the 143gn. At least with factory ammo.
The ballistic calculator tells be that the 143gn at 2550 only just make the magical 1000 foot pounds of energy at 400m. Whereas the 129gn SST still has about just over 1000 foot pounds at 500 metres. Perhaps the 142 or heavier projectile has a place with The 6.5 PRC but not the Creedmoor.
