Well now I shoot about 1000 center fire rounds a year, but actual hunting, I'll check the zero on any rifle I have not fired for a few months or if I'm using different ammo, so thats normally 3-5rds, and whatever I use while hunting so I guess I'm in the 0-20 range.
Target shooting and working up reloads, not related to hunting I would estimate 200-400, mostly .303Brit .308Win and 25-06Rem, and a few 7mm RemMag.
Shooting my milsurps another +500, 7.62 x51 x39 x54R .303Brit
And another few boxes shooting varmits, not really hunting (25-06 and .308)
