The 300 Win Mag with good Prem 180gr bullets is very popular here in Alaska.
But the 338 Win mag with 225gr is what I use most.
A Win 70 with Mcmillian Stock and for the scope I use a Leupold 3.5x10 with the B&C reticle in Warne QR mounts. A real shooter out to 600 to 700 yards.
I handload my ammo with 225gr Nosler Accubonds and Reloader 19 @ 78.0
which gives me 2950 FPS. WW Brass and Fed 215GM primers.
After seeing the big costal brown bears the 338 Win seems even small.
