Not you’re normal what deer calibre should I buy but here it goes. I have been hunting for years for deer and get a deer every year with the same 30-06. Well this year today I just got two smaller deer and think the 30-06 is a little big. What would be the ideal calibre for whitetail deer here in central Ontario? I have a 44 Mag but have never shot anything with it and wondered if it would be any better. If you have another calibre you think is better let me know as I always need a reason to buy a new firearm.
