Virg,
please tell me more about .30 HBR, like what is the parent case you use? .308 or 300 Sav,, is it similar to a full size .308? Is it similar to the .30 BR? What weight bullets are you using?[/QUO
I use the Savage 300 brass which now days is hard to find. But I did stock up. 308 brass is doable but lots of work. 30HBR is more similar to the .308. It is like a 30-47 but with a sharper shoulder. I use the Sierra 125 GR tipped MatchKing bullets, numb 7725. However, at todays match I tried Sierra's 125 GR HP MatchKing's numb 2121, and they shot as good as the tipped version. The tipped 125's are now hard to find. Even Sierra is out of stock. I like the flat based MatchKing's better since my load is compressed. I use'd to use custom bullets, but the long cycle times drove me to Sierra when they started to make flat based MatchKings. In my rifle, they shoot just as well as the custom bullets I was using.
Good luck with your shooting...Virg
