Welcome aboard:
A good used bolt action 30.06 would certainly handle your needs. Scoped of course. If you get a line on one you like, post back with make,model of both rifle & scope and there will undoubably be plenty of opinions.
Here's a link to some shooting ranges in your area, no better place to go and see what's around. I bet your not there very long before you get wind of someone that has a good rifle for sale at a great price or knows someone who does.

I agree with Hammer1 that the 30-06 would be the way to go. A good all around rifle for hunting all types of big game. Just check around at the gun shops for a good used one or new if you prefer. Just try and find one that feels comfortable to you.

You may want to check out Savage Rifles. I bought Savage because they used to be one of the few manufacturers of left hand bolt action rifles. They are one of the more modestly priced rifles. I get very good accuracy from my rifles, 1" or less groups at 100 yards. I have one in 30-06 and one in 7mm-08. The 30-06 is a great round, but I have come to love the 7mm-08. The rifle is lighter and the recoil is milder. The recoil is midl enough that at the shot, I do not lose the sight picture.

I hunt pigs with the 7mm-08. So far all have been 1 shot kills. Most drop in their tracks. The farthest I have on run was 10 yards. I am shooting Remington 140 grain core lokts factory ammo.

All the above calibers are great advice. You would go wrong getting any of the mentioned calibers or rifles.

Welcome aboard. Any of the above would make good choices. You could pretty much go with anything from a 260Rem on up, just pay attention to the bullet you use. Good rule of thumb is a med weight bullet for the cal you select, in standard cartridges. 26 cal= 140gr (fairly heavy) , 27 cal 130/140 gr, 28 cal 140/150 gr and 30cal 150/165gr. If in doubt, use a bullet a bit heavy rather than to light.

We'll send you a bill! We need the money to build Hammerete a new kitchen!

Guess I should explain. She has been cooking and baking and doing dishes in his reloading room and he has had just about enough!!

Could you build that kitchen somewhere other than here? I just closed my eyes and threw a dart at a map and it stuck in a placed called Antelope Oregon !!!!

Oh my God!!!! Sometimes the "Swamp Monster" comes over for a visit and I think ,,,,,,,,,,,,,well it wouldn't be good!

Go buy a quality 30/06 and hunt anything in the lower 48's. Best of luck
