For deer I use a Savage model 111 in the 30-06 caliber with a Simmons 3-9x40 scope (one of the older good scopes). Ammo is the Remington 180 grain core lokt soft points.
For turkey I use a Remington 870 super magnum, 26 inch barrel, bottomland mossy oak, Indian creek black diamond strike choke with winchesters supreme high velocity turkey loads~ 3 1/2 inch, 5 shot, 2 oz of lead. Here is how it patterns with 7.5 shot at 15 yards (I can't find the pic of the 40 yard shot with 5 shot).
For squirrel I use a marlin model 25n with a cheaper (I forget the brand) 3-9x40 scope. Pic of the target at 50 yards:
For targets I like my ruger mini-14. Center point 3-9x40 illuminated cross hairs. (Red/green)
Them of course you need the do-it-all weapon
