I've looked through several other threads in hopes of finding some details but did not find them. Sorry for any duplicity on my part. I see lots of talk about the H4350 powder as well as the IMR4451. Most of the bullets being discussed are the 140's or even the 129 gr. Has anyone had good luck with the heavier 143's or even the 147's? We have shot the ELDX and ELDM in other rifles and they're great.
