1 moose with a 250 grain Speer and several whitetails, I think all with the 200 gr. Hornady SP. I was, actually still am, a great fan of the 270, but a trial hunt with the Whelen back in the late 80's made me think that Elmer Kieth was on to something with the big bullets. They are simply effective in the field. Oddly, the longest kill I have, approx. 300 yards, was with the Whelen on a whitetail buck. I had a Rem 700 from 1987 or 8 that liked about any bullet, but replaced it with a Rem 750 that is a little more picky. I believe that bullet construction is less important with the 35 cal., as velocity is a bit more modest. I would only use an AFrame or Partiton in the 270 on moose, but did not see it as important with the Whelen. so far, experience bears this out. My criterion is confined to accuracy & proper velocity. Good luck.
