I'm new to the sport, I actually haven't hunted in years and just recently finished school so now that i have time I'm looking to get back into it. Anyway I'm looking to buy a rifle but am somewhat confused as to my choices. I'm not willing to buy a .22 because I want a gun I can use for many years to come on large game as well as small. So I've decieded (although not withoout any doubts) on a 30-06 winchester x rifle autoloader. Now first off I'm aware the reliablity of autoloaders is questionable so I'd like to know if I'd have good reason to worry about that gun jamming constantly. Secondly I've read the 30-06 has a wide variety of ammuntion thats good for everything from small to big game ( one of the main reasons I'm interested in this calibre) however I 'd like to know the different grains available and which are best for each species. I'm talking everything from bears (for defence, grizzlys are common where i plan to hunt) to deer to rabbits. If anything here dosent make sense i apologize, im a begginer, please bear with me and I'd really appreciate any help.
