I need to get my Remington 700 shooting a little better and I'm trying to weigh the options. I have pillar bedded it and worked up a ton of loads, still I can't get her shooting much better than 1". I'm sure the factory action and chamber are causing most of the problem so those are going to be squared up for sure...but how much of a difference will a new barrel make? If I have the original stuff blueprinted, rechambered and recrowned can I realistically expect .5 moa? The barrel only has about 200-300 rounds through it.
