I like the 375 but the twist on most of them don't cater to high bc bullets,shoot 270 speers in mine at about 2800,i guess if you call .454 high.
That would work.
I just got a can of 8133 for the 26 nosler,no load info yet from any sources other then to say it is on par with rl33,i got it for the copper cleaning aspect of it plus from what i hear about the eld x I'm going to need all the help i can get.
I went with 26 nosler,i have a 6.5x284, 26 nosler and 375 ruger.
I like the range and comfort the 26 affords me although i have shot a few 300 wm and it seems to me that my 270 speers or the 300 grain dgs at 2800 and 2660 respectivly have less recoil than the 300s I've shot.
