I for one won't use Hornady ammo. I think I posted it elsewhere when someone had a problem with pressure. The box of 270 Winchester brass I have for their 130 gr SST ammo has a MV of 3200 fps. That's a good 150 fps more than any other factory ammo I've seen to include Federal's Fusion and Winchester's Power Point ammo with the same bullet weight. Hornady's ammo crated cratering in one rifle and flattened primers in another.

My usual load for those two rifles and that bullet range from 58.5-60 gr of H4831 and regardless the primer used, none looked like they did with Hornady's ammo.
