I was looking at getting a 700 Remington ADL in 7mm Remington Magnum and would like to use the Action to build a 300 Winchester Magnum. I can pick one up for about $350 new and figured I would sell the stock, trigger and barrel. I wanted to use the action to build a 300 winchester magnum. I was under the impression the bolt face diameter was the same and I wouldn't need extractor work done on it. Any reason why this is a bad idea or is there a cheaper easier way to get a 700 action.
