220 gr for .308Win - any ideas?

Welcome to THR, Mojito4u.

I'm not sure how tough the jacket is on the 220gr Hornady's, and wonder if they will expand at distance, or just punch holes in the game. Not that punching holes is a bad thing. Probably would prove to be good on big boar hogs, where penetration is important.

I think that 1in10" twist is optimum for most 30 cal barrels, as it's worked in the '06 for the last 100+ years.

Regarding Heavy Bullets in the .308

The hands down best powder for doing this is VihtaVouri N550. With this powder, I am able to reach 2700fps at safe pressure levels with the Sierra 190gr MatchKing bullet. I have heard that RL17 is also a good powder for the heavy bullets, but I have not tried it. Since you are more or less venturing in "uncharted" territory, I would find someone who has a copy of QuickLoad, and give them the list of components you will be using, and have them give you a printout of the results.
