Personally I find that surprising however it is there. It is a compressed load.
I would doubt if that is a usable load. The Weatherby is built with long lead for a purpose.
To reduce pressure with max loads. A standard rifle with standard lead will build excessive pressure at max length. a Bi-product of compressed loads
As I stated before the biggest problem is the lack of sectional density with this particular mid bore/light for caliber bullet. However if you could get it to shoot accurately it would make a great long range Light game round.
This is interesting to me because this is VERY close to the 150 gr. Accubond load from my 300 wsm. Velocity is close slightly in favor of the 300. ballistic coefficient is substantially higher with the 30 cal bullet. Sectional Density is virtually the same.
Meaning penetration will be pretty much the same.
That 300 load is very effective on deer sized game and is not dangerously overloaded or compressed.
with the Higher BC the .30 Cal load is clearly a better choice than a light for caliber bullet from a .338
Have fun with your .338 experiment I hope you do not get hurt
