I too believe that something in the 30'ish, up to 40 cal would be ideal for Turkey.
But like your State, my Provinces rules (specifically for Turkey) state "nothing smaller than 20 gauge nor larger than 10 gauge" and you must use #4, #5, or #6 shot (and nothing else - but no specification as to whether it's lead, steel, bismuth or rock salt for that matter) .
Just to illustrate how sometimes "rules make no sense", this very same "Ministry of Natural Resources" rules for Deer with a Muzzleloader have NO RESTRICTIONS unless using "shot".
I could "legally" use a 20 caliber ML for deer as long as I use a round ball or conical.
If I loaded a gun with buckshot it would have to be (minimally) a 62 caliber (not sure how they would interpret a buck and ball load )
So while my "soon to be built" 38 caliber is going to become my "deer rifle" (replacing my 40 cal), it is considered inadequate/not sufficient/not proper for Turkey.
I'm glad we have non-hunting bureaucrats making the rules for my natural resources
Our rules recently (10 years or so) changed from the ancient reg requiring 24 cal or better in CF to all CF (and IIRC 40 or 45 was the ML min, now is 36). Also they "streamlined" the seasons (thank Heavens). Used to need a
Solunar calendar and an abacus to figger out which weapon was legal in the woods on which day...all season long, plus "no hunt" days in the middle! Now Archery opens on a fixed weekend, then ML, then modern and they all run concurrently until the last day. A big improvement. Whoops, there is a 2-day gap in the middle of Archery, don't know why-doesn't affect me.
But that I met a fellow at my ex's HS reunion (2005-ish) and spent most of the evening talking to him. He was a member of the "lobby group" that
leaned on (that's not the terminology they use) the state legislature specifically with regard to game rules/regs. Details escape me now, but I do remember bringing up 3 of the dumbest rules (to my mind) of our game laws.
Within a year 2 of those had been changed (one was the caliber restriction). SO, i am serious about putting in some letters to the right people to get things in front of the legislative body--instead of being blown off by legislative staff.
In the meanwhile, I kinda do what i do and figger what eats good is good. So long as there is no shortage of game and there is no monetary/trophy/bragging exploitation on my part and safety parameters are not ignored, I am a sportsman. But also i would never suggest that others do anything but live by the laws of the printed papers ('ceptin' of course in a survival situation), as that might be considered socially irresponsible. We are a self-regulating bunch.
Thanks for the replies everybody.
