SO lets have an update.
I called Shilen shortly after starting the thread. Ordered up the 1-8 twist, 24 inch, 264 Win Mag in What I would consider a magnum sporter, (I think they call it a number 5) Standard crown, and Stainless. They told me 3-5 months, should be closer to 3 as the 6.5 bore is so hot right now, and they may be able to work me in if they had someone cancel, since my specs were pretty standard.
2 weeks later They billed me, and 3 days after that it was on the porch.
Waited a bit for some other parts to get here and thought I had better take inventory on what I had coming and what I had on hand.
Starting point was a Savage 110, 270Win, Left hand. DBM. No idea on year. I've had it stashed away a long time. When you are left handed you buy them when you see them.
I wanted to keep the standard bolt head, so ordered all the pieces to put together a mag, and sock the standard version away.
Found a super cheap Magnum DBM on Ebay. It didn't have the right floorplate, took all of 10sec to swap that.
Tore apart an old 7Mag that weighs around 17 pounds for banging steel. Never gets used, So I stole the notched barrel nut, recoil lug, would have stole the bolt head but it's right hand. Stashed the receiver away for a rainy day.
Went on to headspace, went good. Never adjusted the Trigger Pull, Didn't check it, but it felt nice.
Didn't have clearance in the barrel channel. I can't find a dremel, and I had planned to paint the gun. SO if you have a week stomach, turn away now.
I went at it with a wood chisel like an angry beaver.
Looks "OK", no body will ever accuse me of trying on this 1.
Also stole a 20MOA rail off the 7Mag. Had the 12x Super Sniper hidden away from a distant Black Friday Deal, Rings have been used but they came with that scope. Butler Creeks were purchased.
Got it all put together, and rounded up Reloading supplies. I'ld still like to find some CCI magnums, 150gr sierras, and H1000 or Retumbo. But I bet I can get decent results with what I have. Brass with the correct headstamp is coming.
There it is, Brass gets here, I can do some testing, maybe hammer some yotes and if we get real lucky, a fall trip to Wyoming.
Enjoy the day gents.
