ISG, here is a link to your states department of wildlife, you should be able to find all the info regarding game laws in your state, ie if you have to wear orange, whether or not u can use rifles to hunt deer, etc etc

looks like you must wear orange during deer season and being only 20 you must take a hunters safety course before you can buy a hunting license.

the 30-30 is a good deer rifle is your shooting under 175 yrds

another thing you should do is talk to your uncle and ask him to spend some time with you and teach you good marksmanship, sounds like he is experienced.
