OK, I will probably get jumped on about this as there are exceptions to every rule.
There is no reason why a 1 in 48 twist won't shoot sabots if a bullet the right length is used. I tried it myself and figured out that a 180 grain 200 grain and 220 grain had the length potential to shoot. Now I never matched the 1 inch and less groups I get when I am shooting well with my 1 in 28 twists but 2 inches is a reasonable group for hunting where shots are normally under 100 yds and I did get 2 and 2.5 inch groups.
