Final Decision Deer Season 6.5 Creedmoor: 140 grain Gamechanger or 143 grain ELD-X?

[General RE LEE]

Folks I have paralysis by over analysis. I have a load shooting a 140 grain Sierra Gamechanger 2900 FPS or a 143 grain ELD-X 2700 FPS. Both sub MOA accuracy handloads.

What would be your choice for whitetail at ranges from 10-600 yards?

140 grain Sierra Gamechanger 2900 FPS. This one!

 

[Creedmoor shooter]

140 game changer at 2900 fps without a doubt.

I think the ballistics at 500y will be fairly similar due to the low BC of the gamechanger. The 143eldx should be easily ran at the 2820-2830 node with 4350 burn rates. Even above 2900 w/ rl26. The gamechanger does hold together better than the eldx from most reading, but no personal experience.

I've tried to push the ELD-X harder with H4350 but I always hit pressure above 41.5 grains 2700 FPS.

On the other hand I have an excellent load with 46.9 grains of Superformance and the 140 grain GameChanger that hits 2900 FPS.

Thank you! I'm definitely taking note of that load.
What brass are you using?

Nosler brass. 140 grain Game Changer seated .020 off the lands.

What's great about it is it approaches .270 speeds for a similar weight bullet but a higher BC.
