I ran two polls recently - The Optimal Deer Round and The Optimal Moose/Elk Round.
The most favoured round for deer is .308, .270 and 30-06

If you can only have one gun it should be a .308 or 30-06. There has been tons of discussions on these two rounds.
I don’t believe in the one gun theory. The “one gun” is your first gun and not you last gun. You will continue to buy more and more…. Ask any member here.
By the way, the Ontario regulation restricts firearms bigger than .275 calibre for small game hunting in the specific counties. Technically, a .270 is .277 and therefore not allowed according to the small game regulation.
I've read repeatedly on here that the .270 is legal for small game in Ontario.
