sorry dude, Those remington 710 are just wrong looking (maybe they shoot good, but I like my rifles to look like rifles not gray plastic + barrel) Sorry Don't mean to insult anyone
2nd, for your purpose of using this rifle, the 300 win mag is a nice rifle / round, but if your going to plink just get a 30-06 or 308 (and those will pretty much handle most large games if you ever took it hunting)
Rifle wise, go into
www.walmart.com and check out thier rifles, they usually have the cheapest prices (if not, they DO match prices of others)
recommendations wise, I don't like to pay alot for rifles and I do like synthetic stock. Umm in the walmart website, they sell mosberg rifles (I think they are called Mosberg ATR) in caliber 30-06 or .270, for only $244, and you can ask ALOT of people here how well those mosberg ATRs shoot, I got one for my father this past x-max, I get anywhere from 0.5" to 1" groups @ 100 yards. If you don't like this rifle, still, check out walmart's prices on the 300 win magnum, you'll like thier prices
