I agree Benhuntin, the .40 isn't an ideal choice for deer but I think the .357 would work well.
A .40 cal. is larger than a .357 just not as powerful but neither would be a good choice for deer hunting
I don't hunt with my .40 caliber, I only carry it in case I come across a coyote, a poacher or a wounded animal suffering But I always call the authorities before I end the animals suffering.
Democracy is two wolves and a lamb voting on what to have for lunch.
Liberty is a well-armed lamb contesting the outcome of the vote.
