The original loading for the 30-06 used 220grain round nose bullets. That's why the 1-10 twist rate came about.
200 grain bullets are still readily available. 220 grain Hornady Round Nose show up in part boxes at gun shows.
I agree that 2700 fps is attainable with 200 grain bullets. The loads given above are well tested by others as well as those suggesting them.
As was mentioned, this is a very stout load. Not unsafe just punishing to the shooter.
The bullets of that weight were necessary because of their construction and of course the relatively slow speeds.
Todays bullets are so good and so well constructed that such heavy bullets are not necessary for even the biggest game available here.
That said, it was a toss up this fall what I was going to take on an Elk hunt. Either a CZ 30-06 with 200 grn Speer Spire Point flat base bullets or a M70 chambered in 338-06 with 225 grain bullets. Both deliver almost identical velocities and trajectories so either would have been more than adequate. The deciding factor was recoil. The M70 wasn't nearly as punishing.
At one time I had several rifles of various makers chambered in 30-06. The only one that didn't do well with the 200grain bullets was a custom rifle with a 1-12 twist rate. It should have been fine but accuracy dropped off with bullets heavier than 165 grains.
The rest, except for a match rifle I put together with a 1-15 twist rate for off hand shooting all had 1-10 twist rates.
Unless it is unusual for some mechanical reason 30-06 chambered rifles really like heavy bullets.
The two rifles I have now as far as hunting rifles are concerned is a BSA with a 22in bbl and a CZ ZKK600 with a 26in bbl. Both are extremely accurate with heavy bullets. That being said they both will shoot bullets as light as 125gr into moa at 100yds if I do my part.
The reason I kept both of these rifles is because they will shoot the same loads in the same manner consistently. Their chambers and throats cast out within a few thousandths of an inch of each other. Very similar basic actions as well although the triggers are completely different.
The starting load I used for both of them was 57 gr of IMR4350, CCI 250 primers, 200gr Speer SP and worked up a grain at a time until I found the sweet spot. I went up to 60grs. 60 grains started to show some pressure signs so I backed off to 58 grains. Both rifles shoot that load into 1moa or less.
I ran out of that lot of IMR4350 so in a pinch, I went to H4831. It proved to be every bit as consistent as the previous powder but needed 59gr of powder over CCI250 primers. It is also a very accurate load.
I never went back to IMR4350 for the simple reason I likely have more of it on hand, all from the same lot, than I will use over the rest of my life.
The 30-06 has become a very under appreciated rifle these day what with all of the super velocity (maybe) new kill em with the first round creations.
IMHO, cartridges like the 30-06, 303Brit, 8x57 and 7x57 mauser and others like the 257 Roberts and 6.5x55 chambered in modern strong receivers will do just as well for the game they are designed for. Mind you if the manufacturers of ammo and firearms had to stick to those mainstays it is very likely they would experience very lack luster sales.
Those old girls just keep on performing every bit as well and now, with modern rifles and components better than ever. Sometimes better than the new creations.
I know I keep going back to them on a regular basis and my go to rifles, other than the 338-06 are chambered for one of those venerable cartridges that just continue to keep proving themselves over and over again. Nothing is ###ier in a firearm than one that does what it should every time all of the time.
