Results: DisastrousI just loaded up 50 rounds of the .309"s in 30-06 cases with 10 each of 8-12 gr of Unique. Going to shoot them tomorrow from my 03 Springfield. That rifle is a tack driver with commercial jacketed rounds.
We'll see what we see.
Thanks for the info.Get some 4831 and Dacron filler. From memory I used to use 48 grains of 4831 and .5 grains of Dacron. The Dacron tuft was placed on top of the powder column. My old time shooting buddy showed me how to do this successfully. We would shoot 10X's prone at 200 yards with our 30-06 highpower over the course guns. It was a blast to shoot offhand also and clean the target! This is one setback when shooting into a head wind though - you will see the fine 'snow' coming back at you. It is no problem though. Make sure that you size your bullets to at least 0.002" over the groove diameter. And use a proven cast bullet lubricant. Oh, and use the Lyman 2 Step M Expander Die - do not flare the case mouths! This is the most important thing to remember for loading cast bullets successfully!
Well, I hoped you'd have better luck. I think I've given up on non GC'd in my 708.Were you shooting gas checked bullets? I'm not.
I am expanding the case mouths with a Lee expander die and then roll crimping.
