Ok so let's throw price out the window for starters if you could only have One and only One custom rifle builder to build you a custom hunting rifle who would it be ?
Thanks,

Your question is intriguing, and it could use a little more detail.
What will the rifle be used for? If you are going to hunt N American large Game at distances beyond 400 yards, I would have a good firearm builder put together a SAKO action with .300 Weatherby cartridge. The .300 Wby can be loaded down with a 150 grain bullet and all the way up with a 180 grain bullet. I know there are 220 grain bullets out there, however, the ballistics of the 180 grain most often provide better trajectory and hydrostatic shocking out to 800 yards.
If you would like to varmint hunt! I would use a SAKO action mated to the .257 Wby cartridge. Fantastic, ray gun like trajectories, with great energy. There are considerable number of projectile weight and designs that will cover prairie dog to Elk.
If you feel you would like more power that the .257 Wby, go with the Wby 6.5-300. It does out perform the Creedmore, by a considerable amount.
There are considerable combinations of powder and bullet weight combinations for reloading for both calibers. I have, and will, harvest Elk at 700 plus yards with my .300 Wby with a single shot. My wife has harvested Deer and Caribou at distances beyond 400 yards with her .257 Wby, usually with a single shot.
Then again, my collection is mostly Weatherby factory built firearms, however I have a few ME-TOO Wby chambered firearms.
I think responses to this will show bullet caliber and hardware can be an emotional based decision. I have been shooting since 1956, with most things from a .22 to .308, 30-06, 270, 7.7 Japanese etc and I have found I can do everything I need and want do with a Weatherby.
