Seafire,
I noticed you mentioned you busted two stocks and screwed up a Ruger 77 shooting a .223 with 55’s and 25 grains of H335.
Care to elaborate?
I’ve been running 25.3 with 55 Hornady sp’s in an AR and it seems pretty sedate. Granted I’ve probably never shot it above 82 deg.
25.3 is Hogdon’s max in a .223 chamber, I’m running it in a Wylde seated out to p-mag length, so there may be a bit more leeway there I’d guess. R-P cases, 400’s.
