I'm looking for suggestions or first-hand accounts on a good, high powered, sub-MOA rifle. This is for target shooting. Ranges will be 300+. I Doubt I'll be shooting more than 600 but want something that's capable of more. That's mostly for "cool factor" and probably not because I'll be shooting that far. The rifles I'm considering right now, to give you an idea of price range, are the Remington 700, Weatherby Vanguard, and Savage 10FLP. I'm looking for 7mm rem mag or .300 win mag. I don't want anything smaller. So any thoughts on these three rifles or any other suggestions would be appreciated. Major factors are price (same range as the three mentioned) and availability of aftermarket parts for customization and accuracy improvement.
