AG-42B Safe Powders

[Schofield]

I am looking for the fastest powder safe for use in my AG-42b with 140 grain bullets. I currently use IMR 4064 in my handloads however I am curious what other powders can be used. What powder do you use when loading for your ag-42B?

I've had good results with H4831SC (43.5 gn) under Hornady 140 grain ELD Match.

37gr h4350 w/144gr Norma bullet matches my sights and cycles great

Slower burning powders can give a higher gas port pressure, and risk of parts breakage(or injury). Fouling from nickel/copper jackets caused some to fail in the past. Keep them clean of jacket fouling.
Just because it's in a loading book, doesn't mean it's appropriate or safe on a 76 year old semi-auto. People have adapted, learned how to load differently for garand(similar problem) .

I used 3031 and 4895 and found there was still plenty of port pressure to run the rifle. I would not use any powder slower than Varget.

Add my vote for IMR4064 and IMR3031 for suitable powders. With the age of the gun I have (and all ofthe rest of them ;-})>> ) I tend to go with a lighter load. If I want to really blast something, I get out the 338RUM.
