Re: 280 Rem with 120 Nosler BT's and H4350.
I have standardized on a Hornady Custom factory 139gr SST load with a nominal 3000fps MV as a hunting load. Although not yet blooded, it's very accurate at 100yd, and the SST bullet seems to have a good rep.
I'm interested in the 120NBT because that's what I had started testing with Ramshot Hunter before the HDY load simply wow'ed me.
Now that you've provided a 139gr load, I'll use that as an alternative ballpark development starting point. Much thanks for your assistance.
The rifle is an inherited heirloom, one of a pair of Ruger R77's which came along complete with dies and brass (Win nickeled primed cases). The other one's a more conventional 22" sporter/hunter. Both are MK I's in very nice shape.
