Here are my thoughts on my next project. I welcome any input on minor tweaks
6.5 Creed
Bighorn SR3 action
McMillan Game Hunter
Bartlein 2b or Brux 3 (fluted for looks), somewhere between 20-22" ( ? What size shank is average? Need to know for the stock inlet I think)
APA bottom metal with a Curtis flush mag
Timney?
Guess of a finished weight?
If you're going with a DBM, consider the TL3 action instead of the SR3. The ejection port cut out on the SR3 looks odd, at least to my eye. The TL3 might be a bit heavier, which may matter to you. Of course if you already have the SR3 action, never mind.
BTW - The DBM is a good idea. I have a SR3 (short action, extended mag box, Sunny Hill BM, 6.5 SAUM) project under way right now. It shoots great, but feed/eject is a big problem. I'm about to throw in the towel and call it a failure.
