Doing my own. Using is Norma brass, CCI primers and testing H1000, H4350 and IMR 4350. So far the H1000 looks best, but marginally. I'm finding my rifle prefers lighter loads. As soon as I cross the middle of the upper/lower loads it starts to opens up but all three powders do well when my loads are just below the middle range.
The tipped TSX has been really accurate but I was just a bit concerned about 130 grain. As I understand, caribou are thinned skinned so a lighter bullet would likely prove successful. I've never hunted with anything under 180 gr (usually I hunt in the West using my 300 Win Mag) on deer/antelope, so, just bit of concern on the 130's.
Thanks for the comment.
