Lets not forget that little thing called powder room, size matters.
8x68s   -    86.5 grs of water
.35 Whelen    -    72.6 grs of water
.338 WIn   -      85.6 grs of water
An extra 14 or so grains of powder is not inconsequential.
And while Bobs long barreled and throated personal custom rifle may be able to achieve such speeds, I would wager dang few factory rifles will and certainly 95 percent of Whelen owners wont ever tread in those waters.

As you know my loads are not hotrodded they are taken from actual certified load data.
The Whelen  already has a long throat  standard. So the loads I use are achievable  in any factory rifle using  proper safe loading practices.
As for my long barrel it is only 25 inches as opposed  to the average 24 inch.
All I have ever done is enlightened  people  that the Whelen  is capable  of far better performance. 
There are a few on this forum that were getting  better performance  than the standard  Whelen  using 4064 and Re15 before I came along. There are even more now that have realised  the benefits  of loading  the Whelen  to its potential.  
I have had PMs from people  on this forum thank me for the information  I have provided and have used the loads in STANDARD RIFLES,  rugers and Remington and achieved the same results  to the point their Whelen  using  these loads have become their go to rifle now instead of it languishing  in the safe in favour  of supposed  better calibers. They have come to realise the Whelen  is now better than it has ever been with more than enough  power and a flat enough  trajectory  to bring it out from its old status as a good woods cartridge.  It is now a cartridge  capable  of longer range  and power enough  to dispatch game at 400 yards  plus if they do their part. It is also capable  of putting a big hurt on game close in with 275 and 310 grainers.
Is it the perfect rifle.
NO it isn't,  but it's a lot better and more versatile  than at any other stage in its life.
There are those that like it as much as me and others that are coming  to realise  what  it is capable  of.
There are others that like it as much as I do the 243, but to each there own and I have no problems  with that. 
There are also a lot of cartridges out there that are loaded to their potential  and reloading  can't match or improve on the factory loads
To be honest I'm getting a bit bored with case capacity  and all the other stuff. Loaded to the same pressures  there ain't much difference  in them.
The old ought six originally loaded with a 150 grain at 2,700fps was a long way behind the 300 win mag. Now we push the same 150gn  in the 06 to over 3,000fps narrowing  the 300 06 velocity gap.
All I have done is using existing  information  for the Whelen to bring it up to where it belongs.
