375-06

A 9.3x62 would offer the same results and be a whole lot easier.

I had the chance to buy a 375-06 Improved a few yrs ago and passed.

I was considering building one as well on a remington 7600. While it may offer a bit better selection of projectiles it really didnt have any performance advantage over the 9.3x62.
 
375 Taylor Chatfield....aka 2.5" magnum family @.375. Pretty common wildcat, 2.5" family fits most 06 actions.

;) Now you're cookin' with gas. I acquired a a custom 700 Remington chambered in 375 Chatfield Taylor :d from a site member a while back. The cartridge is basically a 338 Win Mag case, necked up to .375. Next objective is to get it some experience in the field with its new owner :) .
 
Bevan King barrelled a 375-06 up for me on a Husqvarna 5000 action in the early 70s. Killed lots of moose and bear using it. Friend of mine used it on a bear hunt one Spring, and decided he needed one, too. He had Bevan do one up for him on a 98 Mauser of some sort. Both of us used 270gr bullets at around 2500 fps.

Then I got my first 9.3X62..... :)

I have one built on a ruger number 1, it's a nice caliber to shoot.
One thing I found, depending on the reamer used to cut the chamber is that simply necking up 30-06 cases results in a case that is quite a bit shorter then the trim to length of the reamer spec's, however, repurposing some otherwise useless 270 winchester brass by first full length sizing in a 30-06 full length die, then sizing in a 375-06 full length die results in a case that is long enough to trim the mouth square and be right on the trim to length of the chamber specs

265 grain cast bullets shooting MOA at 100 yards makes it a real fun gun to shoot at the range
 
Wouldnt you need to reduce body taper to have enough shoulder to headspace on? Or would the shoulder be sharp enough?

There is plenty of shoulder for headspacing, the difference between .375 and .366 is only .019" (.0095" per side). A false shoulder is created in the .30/06 case to make 9.3X62, the case neck is expanded to .40", then resizied to .366, or in this case .375, which doesn't completely flatten out the original shoulder, that happens on firing. If you wanted to use a 40 degree shoulder like Mr Ackley made popular, that would gain you a bit more powder volume, but the 9.3X62 already has more powder capacity than the .30/06 due to it's shorter neck-longer body, and you'd probably end up with a shoulder having a Rigby looking profile. The ballistics of the .375 version might be slightly better than the 9.3, since slightly larger calibers tend to drive the same weight bullets faster when both are loaded to the same pressure, but not so much better so as to justify switching, if you're already shooting a 9.3.

My pre-coffee math isn't so good, but this should help . . .
