I am taking my dad on a mule deer hunt in Idaho this fall and he desperately needs a new scope for his Win 300mag. I have been looking at three 1. Pentax Pioneer 3x9x40 2. Simmons aetec 2.8x10x44 and 3. Bushnell elite 3200 3x9x40mm. I am biased towards the Bushnell since i have the 4x12 on my rifle. any help would be appreciated or suggestions on other scopes in this range $150-200. I also looked at the nikon buckmaster 3x9x40. thanks
