re: Deer hunting rifle for a beginner *Update-page 4*

Not sure why I got downvotes, because the 30-30 has been around for more than 100 years and has taken almost every North American game animal. I started out with a Winchester 30-30. Still have it.
So,here you go. Try a variety of ammo. Most times a rifle is particular what you feed it.
You can buy a laser bore sighter for .308. Stay away from the cheap junk on Amazon. Sight mark makes a decent bore sighter. It will help you get on target before you get to the range.
Winchester has an excellent ballistics program on their website. I printed out my ballistics and taped it to my rifle stock.
A sling is a good idea.
A good cleaning kit is essential. Otis makes some of the best. A Tipton gun butler helps with the cleaning tasks.
Good luck and welcome to the show. Hope this helps out.
