130 gr in .270 is plenty for sheep/goat. Shot my first two rams with 100 gr in .243. Bang. Flop. 20 yards and 100 yards approx.
6.5 would be a real good one too. Mine likes 140's but lighter would work, especially with premiums, which are not really necessary for anything, unless for accuracy reasons.
A straight fixed 6X scope is also an excellent choice.
