ok, been waiting on this for 4 months and its been worth it. McMillan A5, ruger MK II action in 30-06. Can't wait to get out and shoot it. There isn't much room between the stock and the barrel, can slip a piece of paper between them but if I press on the stock and I can put pressure on the barrel so I may need some additional relief. Barrel is a Hart and was shooting well before the new stock. Really impressed with this stock. its not cheap but seems like a good investment.
