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

Turns out my 308 and 30 wsm really like the 178 bthp hornady. Had really good performance on deer. In process of reworking load for the wsm due to imr 4451 discontinued. See how 4350 works if I can ever get to the range.

Tagged for reference.

Just as a point of reference. I am running the 178s in high pressure 308 Win loads at 2855fps using 48.2 grains of Varget. They consistantly shoot under 1/2" at 150 yards (max distance from my porch ).
