Re: What optic do you use on your hunting rifles?
Here in Central NY, deer are taken in either a woodland of farmland context.
For the woodland context my guns are either 20ga slug/sabot guns, or my 44Mag lever gun, and these all wear dot scopes zeroed for 70 yards. The ballistic curves for these firearms tend to be surprisingly similar. Shooting opportunities tend to be fleeting, so quick sight picture acquisition tends to become foremost.
For the more open hunting context, I use Ruger MKI .30-'06's or .280's with some older contemporary Redfield 4-12x40 scopes that were mounted on them when my Elder Brother Bill had those guns before his passing. They are generally zeroed for 200yd, which is close to a good MPBR zero distance.
Deer this year appear to be more or less plentiful, just never where I can get to them. I do tend to get a decent naturalist's eye view of the foxes and cute little bunnies, though...
