Hard to fault the accuracy of those 150 Rems in Tim's rifle!
This was the Speer 150 BTSP over 37.0 748, avg 2419 fps, 3 shots 0.665" @ 100 yds:

I have not hunted with this load-- partly because Speer engineers told me this velocity is adequate for this bullet, but just
barely and they'd like to see a couple hundred more fps before using it on whitetail, but mostly because the 125 Ballistic Tip has been great and I don't see any reason to change right now.
I suspect this bullet might be OK at 2400 or so because I killed a bunch of deer with the 165 BTSP in a .308 Win with an 18 1/2" barrel for over 20 years before I ever got around to getting a chronograph-- and the Win 760 load pushed it to only 2510 in that rifle (a Rem 788).
Man, just see how your rifle likes those Fusions, and if it works out, go hunt with it and don't give it another thought. If they don't, you can certainly do worse than green box Rems that Tim used!
Congrats on the .30-30, mine is a close rival to my .45-70 for being my favorite Handi!
