RE: Hornady ammo choices
Hornady's 190 Gr btsp has worked well for me in my '06 and .300 mags. However since the new bonded bullets are available I'd be shooting them. There's a lot of fine bonded bullets available from Nosler, Swift, Hornady, North Fork, Speer, Woodleigh, and others. I believe Sierra don't have any bonded offerings yet!
They're a little more money but I feel it's justified. I bought 50 200 Grain Swift A-Frames (.308 Cal) several years ago and I'm still shooting them. I only shoot them when I go hunting and I'm now using them for deer as well as bigger stuff.
Lest I forget, there's more supporters of the Nosler Partician than we can shake a stick at and that says a lot for that bullet.
