Regarding the comments concerning the 162 ELD-X and H4350: I shoot 45.6 in Rem cases, FGM, at 2.805" and get 2650. That is .6 grains over book max, but my Tikkas have long throats and I worked up. This is over my Prochrono. (And a friend's.) I had three Tikka 7-08s (now two), and a buddy has another. Almost identical velocity in all four rifles.
I also tried Varget, 8298, H4895, and Hunter. My best results were this load and H4895,
Regarding switching to LA mags, I did it in both of mine. It did work, but in my experience the feeding was a little better with the SA, so I'm back to using those. Accuracy is the same (great) seated at 2.805 or 2.95 (IIRC.)
I'd like to try the 150s, but I have several boxes of the ELD, so it may be awhile!
I've posted these pics before, but here is the 162 the first time I shot them doing load work up (Yes, I know these aren't 10 shot groups people want, this was the first time out and I was just looking.):These are with a SS Lite with a SS 3-9.
