here is my assessment of the 300 winny, it is definitely a multi-purpose cartridge, an absolute hammer at close range on anything that eats grass, will take the big bears effectively with tough bullets.
Where it shines is with a big scope a long heavy barrel, and a big skinny bullet, put a 30" barrel on one, a repeatable scope, and a bullet with a BC approaching .7 and its a totally different beast.
