" All the bull barrel adds is weight and the wooden stock will cause you accuracy problems due to swelling/warping." I am going to have to disagree with that. I have an Ultra Varmint in 243 Win and the heavy barrel makes it much easier to shoot off hand, cuts down on the effects of wood swelling (which I have never found to be a problem anyway, especially on a single-shot rifle) and is more accurate than the thin barrels if for no other reason that they are more steady.
