Throat of 22/250 is fried

colony varmints

Right now I can get a #5 contour 12" twist Muller works bbl. Previous bbl was a #4 contour.(Predator rifle,sporter stock) I'd really like a #6 contour,but might have to wait a few months .Is the difference worth the waite ? More varmints than predators around.I want to shoot 53gr V-max up to 64gr Berger bullets)

If you shoot from a bench on colony varmints heavy barrel is better and more forgiving in my humble opinion.
