I was going to do some stuff with a savage long action, but I'm left handed so everything would take way longer. Mcmillian said they would do a stock for me, but I had to send them the rifle, so they could make sure the inletting was right. I also assume with your accustock that you have the factory dbm. That limits you to 3.500" coal length if you want to use it when you modify the rifle. For the length limit on coal, I would reccomend going with one of the wsm rounds. That way you can seat the bullets out to optimize it and still fit in your factory dbm with the heavy bullets. I will probably do a 270 wsm on a savage long action some day and have it throated for the 170 berger eol. When I measured the coal with that, it was about right for that factory mag. I would imagine that a 300 wsm with a 215 berger would run nice in that too.
