Far as Calibers Go I dont really care. Shoot something you like and can buy ammo for.
6.5 creed, .308, 223 would be my recomendation.
.308 will kill any thing in north america and ammo is easy.
My personal opinion is that "OUT OF THE BOX" $500 or less, the Rifles I have had the best experiences with are the HOWA or The Weatherby Vanguard by legacy sports.
Have never had one that would not shoot at least .75moa, some much better, and you can get them in Many Configurations.

They have good bottom medal and magazines and just "FEEL" like a solid rifle.
Actions are solid and Slick
I Have them in 7mag, 308, 7mm-08,6.5 grendle and .223 but not a creedmore.(I shoot 6.5x47L in my 6.5 rifles)
Howas come with a better stock and have a descent 2 stage trigger.
The Ruger Americans Also Shoot Good and come in lots of calibers but they just feel "Junky" to me.
I have one in a stockys stock that feels MUCH better but then you are over $500.
Put one of each in your Hands and you can feel the difference.
I have had a Remington 700 in lots of calibers and still do but the newer ones that are around $5-700. , have not shot as well for me and my friends.
Watch Gunbroker for deals on Howas or Weatherby Vanguards.
Bought a New Series 2 Weatherby Vanguard 22" Heavy barrel in .308 for $379 shipped for My Nephew at NORTHERN FIREARMS.
Just Checked they still Have them.

This Rifle shoots .6 moa at 150yds with black hills Match 168 amaxs.
All my other Howa calibers except the 6.5 mini, I paid less than $440. shipped
Just my opinions, but I have bought and shot all the rifles I am discussing.
(Have a lot of grandkids and Nephews)
Good Luck
