I have a S&W model 1500 30-06 I don't shoot any more and want to rebarreled it. It favors the heavies pills one can find and want to shoot something under a 150 gr. I also was considering necking it down but I'm not sure I want to put the $$ out on custom dies. I'm looking at moderat hunting ranges of 200 to 500 yards. Any advise would be appreciated. Thanks
