I too, can't see why anyone would choose a 250 over a 243. However, no one has ever explained to me why one calibre is exciting, ###y, or whatever, while a similar calibre is boring!
Originally, the 250 was called a 250-3000. The designation being the bullet was supposed to be travelling at 3000 fps. We later found out,(speaking for myself) that it was only the 87 grain bullet that was supposed to be getting 3000 fps.
On the other hand, I had accurate loads in my 243 with a 100 grain bullet going in the 3100 fps range.
Ballistically, a .257" diameter 100 grain bullet bullet going about (even) 2900 fps, is quite inferior to a .244" diameter bullet going about 3150 fps.

besides cool and slightly more powder efficient there is no rational logic explanation given sofar to pick a .250 over the .243.
The .250 gives frequent case separations due to the tapered shape of the case, meaning only few reloads.
This was discussed on 24hourcampfire under ask the gunwriters comparing the .257 Roberts to the .250 Savage.
Since I have been considering the .250 and the .243, I tend to lean presently more towards the .243.
Main reason for me would be very low recoil rifle sufficient for deer.
The .243 can be loaded up with good accuracy around that 3000 fps.
Can the .250 be loaded up to 2900 fps with good accuracy?
Seems it lies more aound that 2800 fps mark.
The .243 seems to be adequate for deer out to 300 yards, with good broadside shots and good bullets.
Perhaps the .257 Roberts is the one to get, since it has very low recoil and is good for deer and then some. Only chambered by Ruger presently I believe.
Anyway, I got something to think about until next summer.
Wayne van Zwolle writes about the .250 as good for deer out to as far as 200 yards with good broadside shots.
If I spend money on a rifle and scope getting around or over that 1000-1300 dollar mark, I want something with a bit better reach on deer then 200 yards.
