Powder = H1000, H380, and Varget
Primer = WLR
Bullet = 130gr Hornady SST, and 130gr Sierra GameKing
With reguards to your components, I have only used the bullets , cases, and primers for my .270 Win. I have used H-4831, Imr-4831, Imr-4350, IMR-3031 and H-4350, as well as a few loads using RL-19 and 22. However, by an far the most accurate load I have ever developed for my rifle was using 46.5 grs of IMR - 3031 and the Nosler 130gr bullet. As for which bullet, it really didn't matter they all shot lights out with this load generally grouping 5 shots well into 1" at 200yds. This load just hits 2800fps from my rifle and was developed for my mom to use, so recoil is nil. IT has taken deer and hogs out to 380yds, all with bang/flop results. I have worked up a couple of other loads as mentioned for specific uses, but for hunting in general this load is always a first consideration.
I just started some playing around with the 130gr Hornady this past year as I got a pile of them for a decent price. Figured they would be decent for some longer range loads for hogs. However, I never got anything that I was really happy with. Not that the bullets were the problem, just didn't have much time to mess with it. Overall, it has been found that the 4350 range of powders show a generaly better overall accuracy and are more widley used for this particuler round. This is not to say that a whole host of others cannot deliver top notch velocity and accuracy, only that that particular burn rate seems to favor this bullet and case combo.
Hope this helps,
