Reduced 223 using H4895 (AR2206H) 55g

[JPSauer]

I will be creating a ladder load to test accuracy at 50m for reduced H4895 (AR2206H) loads with a 55g Nosler Varm HP.

Brass: ADI
Primer: Fiocchi SR
Projectile: Nosler Varm 55g HP
Powder: H4895 (AR2206H)
Load Max: 26g
Loads will be from 60% in 5% increments, 4 shot groups to 95%.
Barrel will be allowed to cool between shots.

I will also test 2 groups of 70% and 80% with Winchester SR Primers to see if there is a difference.

Posting results this week (hopefully).

Rifle used:
Howa 223 20" Varmint.
Off rests front and back to minimise shooter error.

Range is indoor so wind is no issue.

Just hoping some data would be interesting to someone else. Do not replicate without consulting a reloading manual, load at your own risk.

Do you have their notice for downloading h4895... I swapped phones or I'd post it...

Yes it says that 60% of max charge where H4895 is shown.
