Has anyone tried to use Sierra 90gn.varminter for 270Win. I bought a box to try with my xl7. Would appreciate any ideas on weather they shoot good...not so good. If it has worked what for ya what was your load? My Lyman 49th says that AA2700 was their best powder with powder charges of 50.5 being the min and 56.0 being the max. Any other ideas will be appreciated.
