Very good information here... you've got all the good input you need. Savage, Stevens and H&R are your best options. As the price goes down, so does the quality, but none of the three would I shy you away from. I own several guns made by each manufacturer and still reccomend them to friends.

Look over the prices on those various models andchoose one that fits your budget .223 or 22-250 will work fine- good luck.
