I've shot Roe deer with 120 NBT, and Sierra 140gr GK great results. Texas whitetails with 125 Part., and 140 Part. All with good results.
I've chosen to use Horn. 129SP his year for pronghorn, and muleys, but Nosler 125Part. were hard to pass up.

A good 140gr bullet is the best all around bullet for 6.5x55, 130's come into favor when having to use short action rounds like 260, Creedmoor,or Grendel.

I've hunted with a Swede for 20 years all over the world.
