Well, if you want to buy anything for it you would ask for a 7mm/08 Ackley Improved...not a 7mm/08x40.
7mm-08 Remington Ackley Improved- MidwayUSA
Same goes with reamers.
Just sayin.
Not to start an argument, but as I said, not everything that has a 40 degree shoulder is an Ackley
there are plenty of 7/08x30o and others. what would you call them? If you called it a Ackley you could mislead the owner because most people relate the Ackley's and the 40o shoulder because that was his favorite shoulder angle and the use of the wrong ammo could be attempted.
There are many different 280 Remington AIs for example, and the best example currently is the SAAMI 280 AI by Nosler. It is called that Because Nosler had it certified By SAAMI and it is different than all other 280 AIs. As A gunsmith, It is a requirement to place the cartridge designation on the barrel and it has to be the exact description of the cartridge if it is a SAAMI cartridge, There description is to be used. If it is anything other than SAAMI, that has to be part of the description. Any dimension difference like tighter neck, shorter neck, different shoulder angle, less or more body taper, ETC has to be part of that identification or at least the Wildcat name to let the owner of the rifle know that it is not a SAAMI chamber.
SAAMI does not list a 7/08 AI even though some of the die makers make dies for the 7/08 x30o
or the 7/08x40o and you must know what the dimensions of the dies are when you order a reamer.
for now, the dies are the most commonly used 7/08x 30 or 40o that have been used for many years but if someone submits there own version to SAAMI and it is excepted as the standard, All of that may change.
One more time, The reason it is called a 7/08x40 is Because it is not a SAAMI cartridge and PO Ackley never submitted or designed a 708 Ackley. In fact if they wanted to standardize it and call it a 7/08 x 40 that would be the barrel designation if in fact that was what it was chambered in. so for now gunsmiths are required to mark the barrel 7/08x40
because it is not A SAAMI cartridge and the description matches the cartridge and tells the owner that it is NOT a 7/08 but something different and will require different ammunition. (It is not a TEXAS thing, just a matter of being correct)
JUST SAYING.
