Filaman (and all others),
Great posts... I'm enjoying this immensely.
Admittedly, I've been stepping this way, and that, thinking I needed the horsepower of the 25-06 and/or the 270 (of which I currently have of the latter and formerly had the 25-06 A.I. at one time) for the longer work. That 25-06 A.I. was a Hotrod and a Deer Slayer with its preferred 100 gr NPT and 115 gr NPT.
Early on someone said, "6 Creed."
Being my donor is LA, I honestly had not considered dropping down in bore size - BUT - I am a handloader, I have case forming experience - And I am liking the performance of what I am seeing with the 105's and 107's - and the options given in that caliber such as the 85 TTSX and the Partitioned and Bonded offerings as well. LOTS to Like.
And it clearly gets recoil down.
Without any other changes, seems it would be incredibly easy to neck down the 25-06 (or even the 270) to 6mm and run with it.
I really Like That Option.
The .240 Weatherby is the same thing as a 6mm-06 which is essentially what you're describing here albeit with belt. But necking down the .25-06 or .270 would do it without a belt. May be a good choice. Just be ready to buy more barrels. That's an overbore from hell and would be a barrel burner. Depending on how much you shoot you might be buying a barrel every year or so. But if you don't mind that it should be a very hot number.
