Accuracy International- 300 WSM - 178 ELDX - Load Data

[hafejd30]

Looking for load data on what worked and velocity you’re seeing

I plan to run

Bullet: 178 ELDX
Powder: H4350
Primer: CCI 250
Brass: Lapua

AIAT Rifle with 24” Bartlein- Long range deer killer

These are dummy rounds loaded .020” off the lands. See any issue with the amount the bullet seats into the case?

I have had VERY bad pressure issues with hornady bullets in my AIs but both had factory barrels. Work up carefully.

I run these 178’s in my AT in 308 and have for years. So was hoping to try them

But I’m open to suggestions on what to use. I went Saami spec because I was worried about mag length issues. Wonder how a Berger would measure up?

 

[MK20]

Weird. Mine popped primers at starting load with those bullets.

If you ever want to buy a couple flats of the 178 BTHP let me know. I have about 6000 bullets I can't use, lol. They shoot fine in everything else but my old LW barrel HATES them.

My 308 is a LW 1:12. Mine are the ELDX

 

[MK20]

Yeah. Eldx and the BTHP differ only in tip construction, and will shoot to the same POI out to distance in my rifles that shoot them.

I stopped at the shop I shoot for tonight and picked up some Berger 185 VLD and 185 Juggernaut’s to measure up this weekend
