If you want to see some very accurate "hunting" type rifles, have a look at big bore silhouette rifles.
The rules require them to use sport profiles and they shoot 10rds per relay. They can be superbly accurate.
contour does not determine the accuracy potential of a barrel. only its ability to withstand shooting heat before warping.
target rifles will use the heaviest and longest barrel that will make class weight. Why not?

There are numerous barrel makers in Canada. Smith, Gaillard, King, McLennan. Any of these can make a good barrel. - dan
