RE: what .270 ammo would ya recommend?
When I had a .270 - I've since sold it - I used PMC 150gr, rem Core-lokt130gr, and some federal premium 130gr (on sale!). All killed deer. Usually bought core-lokts.
don't think it matters most of the time - .270 is a pretty potent round. I use a muzzleloader now, but have a real jones for a Marlin 336....
