Well, darn you guy's! I just picked up a box of the 154's to try in my new 7X57. What powder do you guy's prefer with this bullet?
48.0 grains of H 4350 works for me. In fact, that is my load whether I am shooting 140s or 154s. It is a little on the mild side for 140s but it still gets them to over 2800 in my rifle.
That would be too hot in my Ruger M77MkII. I max out at 47 grains with the Speer 145 grain bullet. I'm not poo-pooing your information, just advising folks to start low (as always).

I started to add that it is a little on the warm side for 154s. I don't think it is dangerously so as that there are no obvious pressure signs and it is in line with some other data I have seen, but it might be a little warm. On the other hand, it is nice having one powder charge for all the bullets I shoot in that caliber.
It is hard to get in trouble with the 4350s. I have heard that a lot of people used to load 30-06s with those powders simply by dipping the cases into a bunch of powder and shaving it off at the top of the case.
