I use 46 grains of H4350 with 140gr speer hot cor or 140gr ballistic tips in my Ruger M77. It runs from 2775 to 2800.
I always said I get around to load the speer bullet in one of my 10+ 6.5's. Never have tho. You have any good hard use you might add to the topic. Sorry to hijack, thought it may help other also.
