Can't make up my mind. I have 2 favorites.
338 Federal built by Mickey.
7-08AI also built by Mickey.
I alternate usually between these two, and every season I make a resolution to take one of the following into the woods. 221 Fireball, 223AI, 22-250, 243AI, 250AI, 6mmBR, 270Win, 300RUM, 450 Bushmaster. The 375H&H & 458Win don't get out much, except for range sessions and the occasional bison hunt.
But it always seems to be one of these 2 that comes with me....................
