RE: win silvertips
I guess the bullets are fine, but I never could find a gun that liked the ammo.
Browning Stainless Stalker .270 w/ Winchester Supreme BST = 2.75" groups
Remington 700 BDLSSDM .30.06 w/ Winchester Supreme BST = 2.97" groups
Browning White Gold Medallian .300 Win Mag w/ BST = 3.25" groups
All the guns listed above much preferred Reminton Core-lokts, Federal Premiums, or Hornady loads over the Winchester loads.
I haven't tried them in my Tikka, and probably won't.
