I have a Ruger American Predator in 6.5 Creedmoor. The barrel is not a bull barrel, but it is heavier than the standard hunting weight, the barrel is 22 inches long. The rifle weighs 6.6 pounds. The twist is 1:8 and the barrel is threaded for whatever you decide to use, brake or suppressor.
Although I have access to 1000 yard range, at my age (70) I prefer to shoot in a little closer. With a Burris Droptine scope on it(4.5-14X42), and my own handloads, I consistently hit 3" by 3" plates off the rail at 400 yards. I couldn't ask for more.

Comparing apples and oranges, I also have a Savage Axis, with a timney trigger and heavy factory barrel in 22-250 with the same scope on it and for accuracy, using comparable yardage 100, 200, 300 etc., the Ruger outshoots the Savage. Just sayin.


OP (Willy)...the barrel length will give you just a hair more velocity, but won't affect accuracy.

Happy Trails!
