Need Help With 375 H&H with 270 grain Woodleigh Projectiles.

[Aussie Hunter]

Greetings from Australia.

I am hand loading for a Sako AV in 375. I will be using 270 grain Woodleigh Protected Points and ADI 2209 powder (sold as H4350 in USA).

I can’t seem to find any consistent data for my chosen combination as the data in my current resources varies considerably. The ADI manual is using a 270 Grain Barnes TSX bullet which due to the solid copper construction always shows a big variation to standard bullets. Another manual has much higher powder charges but the projectile is not specified.

The overall loaded round length is 3.554 inches, Remington brass, and Cci 250 large rifle magnum primer. The rifles has a 24 inch barrel. If anyone has suggestions or Quickload data, it would be appreciated.

I'm not sure if it's any help , but here's what I have .

only 2 of my books showed H4350 powder . one book has a flat base bullet , the other book a boat tail bullet .

Still on my first cup of coffee and data sheets are in the shop; However, I’m loading 78 grains of H4350/300gr swift A frame and 300gr Partition getting between 2630 and 2650fps. Consistent 1 moa out to 300. About the same overall length. A place to start anyway. I’ve never used Woodleigh bullets.
