Yes sounds a bit familiar. Something like this?
Ya know the 7mm STW is a great round no doubt but why not add a bit more Horsepower and cut that sucker for my hot 270 AM? A lazy load will get you 3300 fps with the 169.5 gr ULD RBBTs!!
Only problem is that with the Savage receivers, they are not wide enough in the mag box to allow a 270 AM repeater. Still for extreme range shooting this is not a big deal.
The stock on my rifle is actually a factory Savage Laminate stock which I ordered from MidwayUSA. They have them in stock ready to ship, quicker then boyds and actually very good quality. I would recommend removing the factory pillars in the bedding and have the job redone as the factory Savage pillars do not even contact metal on both ends, at least the ones I have worked on have not. Have these replaced correctly and you will get much better performance!
On the 7mm STW front, you ever consider getting one of the new 1-7 twist that I had Dan tool up for for my 7mm Allen Mag? these will shoot the huge 200 gr ULD RBBTs as well as any lightr bullet such as the Ballistic Tips or Accubonds.
This barrel would destroy a conventional jacketed bullet but I feel for a light bullet option the 160 gr Accubond would be very hard to beat along with the Bonded Core bullets from Wildcat Bullets.
Would give great results with this bullet as well as offer true extreme range performance with the 200 gr ULD RBBT.
Just another option. I like your choosing the #7 contour. This is a great barrel contour for barrel stiffness.
If I may, I would make one other recommendation, whoever you have do your rifle or if your doing your own work, if your going to accurize the receiver which I highly recommend, have the barrel fitted like a Rem 700 to get rid of the barrel lock nut system.
This will solve some bedding issues as well as give the rifle much cleaner lines. IF you do this make sure you order a barrel with a shank diameter of 1.250" and not 1.200 or 1.175".
This is the only way I fit the barrels for my customers for the Savage in high performance, large cased calibers.
IT has worked pretty well with my 270 Allen Mag!
