RE: Good .270 WIN cardridge ?
I don't really know of a bad one. Just depends on what bullet your rifle likes. (groups best with)
130gr Winchester Ballistic Tips
140gr Winchester AccuBond
130gr Winchester Power Point
130gr Winchester Power Point Plus
130gr Hornady SST's
130gr Remington Core Lokts (or 150gr.)
Any of the Federal loads.
Personally, in my rifle, the Ballistic Tips were the most accurate. This year I am shooting the AccuBonds.
I really can't really think of any .270 bullet that wouldn't work at 150yds. 150yds isn't far for a .270 at all.
