What is a good rifle that can be had for less than $500? After the initial purchase I plan on adding and changing things on it to take it from a good rifle to a great rifle. Shots up to 1k yards would be cool and I do have a place to go to take shots of that distance. For now I want to get proficient with 500-600 yard shots. What would you recommend for a basic rifle for less than $500 that could be upgraded later? This does not include optics, I have additional money for that.
