Hey guys, first post here, been checking out the forum for a while. Anyways, I just bought a new Remington SPS Varmint .223 that I will use for everything from squirrels, pigs, coyotes, deer and whatever else I can throw lead at, at ranges from 0 to 400 yards. My question is what sort of scope should I top it with. After doing quite a bit of research I am pretty sold on the Nikon. Now the question I have is power. I can only afford about 300 bucks so that limits me to either a Monarch 3-9x40 or a Buckmaster 4.5-14x40 (or a Burris Fullfield 4.5-14x44). Will a 3-9 suffice for my long distance shooting (taking on squirrels at 400 yards) or am I going to need to step up to the 14 power to shoot at that distance?

Thanks in advance
