The other reason is that so many 6mm and 6.5mm barrels (including those on very "affordable" factory rifles) have faster twists for longer, heavier bullets there's really no point in fast-twist .25 barrels, unless somebody just likes to shovel sand against the tide.

I had a .250 Savage and a .257 Improved built a few years back but I use nothing heavier than 115-120 grain bullets in eithere
I had Krieger build the .250s barrel with a 1:9 twist barrel but the .257 has a 1:10 twist barrel. both stabilize 115-117 grain bullets but not sure if the .257 will handle 120s or not. I really don't know if I care or not because it kills just fine for what I built it for with 115 grain NBTs.

What goes up must come down, what goes around comes around, there's no free lunch. Trump's comin' back, get over it!
