Sorry @Danny as per the comments by other fellas, I meant the 90gr ELD-X which hasn’t arrived here yet

So to answer your question, No.

The two 6mm ELD-X are good bullets to use the JBM stability calculator for. Test the theory.

103gr ELD-X: BULLET OAL 1.258”, tip length 0.14”

90gr ELD-X: Bullet OAL 1.104”, tip length 0.14”

The 103gr bullet was designed for the 6mm Creedmoor 1:8” twist.

There are a couple of fast twist .243 rifles that will stabilise them, the Remington .243s with its 9.125” twist is right on the limit at 2850fps.

The 90gr ELD-X is specially designed for 1:10” twist barrels.

After lots of American shooters complained about there not being a ELD-X for the 1:10” twist .243s, and the fact that Sierra put one on them with the 90gr GameChanger, Hornady designed the 90gr. They are a few months behind the 90gr GameChanger and we aren’t seeing them here yet.

I asked a friendly Hornady tech about this. He said that the jacket thickness is proportional to the calibre, i.e. the bigger the calibre, the heavier the jacket. So the 178gr .308 is quite tough, the 6.5mm slightly less so. That has certainly been my experience of those two. So I am expecting the 90gr ELD-X to be fit for purpose, which was described as “whitetail” by the tech. If it performs like the others, it will shed one third to half its weight in little bits in a cloud of damage, and the remainder below the little lock ring will exit.

Whitetail bucks are highly variable in weight, but I normally equate them with a good fallow buck or red spiker or yearling meat hind.

Only one way to find out though.
