My first was a 55lb yearling doe that I shot when I was 22 years old. I'm not gonna say I'm proud of it, but it was my first and I wouldn't have passed it up. Here in Louisiana, unless you're on a management area and there is a bucks only season in progress, anything without spots is legal. A button buck can easily be mistaken for a doe and being your first kill, it is easy to not realize how small a deer is. Personally, now I will not shoot anything that looks like it's less than 100 lbs. By then if it is a buck you should be able to see the antlers clearly therefore avoiding shooting the button bucks
