Most accurate .277 bullet in 1:8 twist Shaw barrel 270 win, hunting?h

I have a 270 win and a 270wsm with 1-7 twist.
Both rifles prefer different bullets even before I had the faster barrel put on the wsm.
My 270 win likes the 130 gr partition and accubonds and will shoot the Barnes 130 ttsx bullets to almost the exact point of aim with 3 shoot groups being right around 3/4 moa pretty consistently. And it also does just as well with the speer 150 gr hot cores. While it will not group with 130 gr Serra and 145 gr eldx.
The wsm does really well with 165 gr accubonds and 175 gr game changer bullets.
I think you're just going to have to experiment with different bullets to find what the gun likes. As for powders I have had good results with H 4831sc, Hunter, 4350, v-165, magpro, Retumbo.
For the 270 win my best load is with 59.5 gr 4831sc and 130 gr accubonds.
For the wsm it's retumbo with 165 gr accubond.
Good luck I don't think you should have to hard of a time coming up with a bullet it likes.
For me I would try some cheap speer 150 gr and some 165 or 175 gr bullets.
 
The 277 Fury (commercial brass case) is very close to the same as a 270-08 AI which I've been interested in for some time. McGowen (don't know about the other barrel companies) is offering it as standard chambering, and the 270-08 AI 40* as a custom chambering. So, the Fury would be less expensive and would avoid fire forming the case. My question, though, is which brass cartridge case would you use to form Fury brass? Could it be as simple as neck sizing a 7mm-08, or enlarging a 260, and then running thru a Fury forming die?

As a courtesy to the OP, you might want to start your thread instead of hijacking this thread. Cheers!
