Reduced .223 Rem Loads

[4090Sharps]

Does anyone have a reduced .223 Rem load they'd like to share?

I'm looking to down load one of my straight pull 223's for an ultralight predator/fur-friendly rifle in 22 Hornet-level velocity until I have an ultralight 17 caliber AR barrel built.

Lyman has some lower pressure, reduced speed, lead bullet loads which can get me started using some powders I have on hand like AA #9, Unique, and IMR-4198, but I would appreciate hearing recommendations from folks here.

But good luck finding Bluedot, right?

No bluedot
Unique can be used but 4-5.5 grains but be careful. Research first.
Different pistol powders can be used.

I found some older Handloader magazine data that used 8.0gr Unique under a 40gr Nosler ballistic tip and cast loads go a bit higher in my Lyman book (maxes around 10-12gr iirc, but away from my books right now). Not saying I would go higher, but the Lyman data was constrained in those max loads by speed for cast, not pressure.
