Michele Eichele - nice post on the 300rum - great info
As the bore gets bigger the longer the barrel life will be. All other things being equal.
The 300 will have a longer life than the 7mm. The 338 will last longer than the 300.
The 338 also has a smaller case, so it burns the barrel that much slower.
