All right I have been wanting to know the answer to this type of question .
Why is it to big of a caliber ? I do know why you don't want to use a small caliber . It's inhumane cus it's not likely to bring the bigger animals down right away . How ever you shoot a deer with a 50 cal , it's going to drop it like a bad habit .
Now I do understand there is alot to consider when choosing a rifle and caliber for hunting , velocity , trajectory , size & wieght . How heavy the gun will be when carrying and shooting it .
In general I would think bigger is better . ( bullet )
The only thing I can think of as to why you may not want to use a bigger caliber then needed is , The amount of damage to the meat the larger caliber would do .
Please help me to understand thanks
