I am giving up on a Ruger Hawkeye barrell in 257 Roberts, shipped back to Ruger and they already replaced barrell, small to no improvement. I have 4 other Bobs in pre64, Kimber, Cooper and Remington and I know all challenges to a quarter-bore. Is the Ruger Hawkeye reciever worth rebarrelling with a Hart barrell, or are there inherant accuracy issues with this receiver. Always wanted a 257Roberts Ackley Improved and wanted to ship rifle to Hart for a #4contour with a 26"barrell but would that configuration be unbalenced and barrell heavy? varmint and hunting only. thanks,John.
