If it was one I put together for myself...
24 inch.... same with the 260 Remington...
I prefer the long barrel... if I can't hump it out in the wilds, then its time for me to just quit hunting...
Although If I didn't have a couple of 260 Remingtons, I could see a Winchester Featherweight in 7/08....
but then my Featherweight in 7 mm Mauser would get jealous I bet...
When Winchester came out with the featherweight in 1952, the barrel length they chose was spot on. Been great ever since too. Even works on the 7mm08. Mausers can get jealous all they want..
