While my experience with the accuracy and fouling of factory barrels has annoyed me. I have to admit that even the accuracy produced by factory barrels have been good enough for memorable hunts. For example, I shot a mule deer at about 20 feet right under the chin while it was looking at me over a mesquite bush after a five-hour stalk. On my first trip to Afirca, I killed a bunch of game with one. Though, the Africa trip started in a pretty rocky manner with my scope getting knocked off during the airplane ride and then expending half my ammo trying to get it sighted back in because of the combination of a skeptical PH, 2.5 MOA and Leupold's less-than-stellar tracking.

Both those hunts were with 2-2.5 MOA .30-06 Higgins FNs. The Africa rifle now has a Douglas (or maybe Shilen, can't remember), 338-06 barrel, Meopta 6x42 and is a tack driver but hasn't been hunted since. I need to take that rifle back to Africa.
