280 AI with 175 ELD-X Question

[Chopperguy]

Helping to develop some loads for the 280 AI using a variety of bullets.

We've been interested in trying the Hornaday 175 grain ELD-X. Intended as a deer and possibly elk hunting round. Thought it may be a possibility as a step up from the 163 grain variety.

Has anyone tried this bullet in the 280 AI? Velocity results?

Haven't seen much loading data out there for this caliber/bullet weight combo so just thought I'd ask here.

Any help would be appreciated.

I have tried both in 2 9 twist 280 AI's and the 162's shot better in both. H4831sc was the best powder I tried. I was at about 2900 fps with the 162's in a 24" barrel

How many grains of H4831sc with the 162eldx? Just about to load with that combo. I have a 24" 9.5 twist.

I started at 57 grains and worked up

I'm now leaning towards the 162 version for this rifle.

Looks pretty easy to get them t that 2900 range.

Not enough difference with the 175 to bother for the game sought and performance at the ranges we expect to shoot.

I've had great luck with the 143 ELD-X in my Creed on a bunch of game from pronghorn to red stag in NZ. This 280AI should be even better.

I've got a bunch of 4831 SC, H1000 and some 7828 to work up some loads and find the accuracy/speed node for it.

Thanks for the input.

Haven't played with the 175 much but it seems like they don't work in my rifle near as well as the 162-168s do. The 162-168s are awesome in my rifle. 4831SC. 2981'sec for the 162 in a 28" barrel 9x.

Berger 168 VLD's backed by 7828 SSC.
