Anyone have any load data for 425 A-SQ Express? Specifically for the CEB 257gr FB Raptor for Elk sized game.

I tend to go for the obscure and obsolete that no-one else has or even heard of.

Pac-Nor sent me a chamber drawing from JGS and I have the A-SQ load manual. The drawings are nowhere near the same except they are both 2.5″. The 423 Belted Express in AG is 2.85″.I have to assume the drawing in the A-SQ manual is the A-SQ version, and there is some load data as well albeit for the 400gr only.

I don’t have Quick Load. I don’t know why, I just haven’t pulled the trigger on it yet.

I’d like to have this rifle built, but there is no point if I can’t find load data.

COTW contains some load data for 350gr and 400gr .423" bullets for the 425 Express (300 Win Mag case shortened to 2.550").
