im a 20 year old in florida.. i want to start hunting again.. i hunted when i was younger but my father passed away during my first hunt ( heart complications ) and i havent hunted since but since my dad loved hunting so much and i love hunting i decided to get back into it.. i dont remember many things about hunting so if you can help me out at all i would really appreciate it..

im getting a browning xbolt 30.06

i ordered a 3x9x40 carl zeiss conquest scope to be mounted on the 30.06 im going to buy.. what do i need to know before i go in there with this scope? will bass pro shops mount the scope and bore sight it for me? and from there how do i sight in the gun or shoot it to make sure its accurate? what kind of bullets should i use? id like to know some things about it before i go in there just so i know what im gonna need to do.. ( im just confused because of the browning scope mounts are different sizes and i dont know what that means or what grain bullet is best to have.. ) any advice on anything i need to know would be appreciated.. ive got alot of my fathers old guns that im going to start using as well but since ive had my son i wanted to get out on the trails and be able to teach him everything about hunting.. thanks!
