We all know that there are "barrel burner" calibers such as 264 Win Mag, 22 Swift, 204 Ruger, 300 Wby, 30-378 Wby and so on...
Some of there cartridges are notorious for their very short barrel life (in terms of rounds fired) despite special treatment in the manufacturing.
All of them develop MV well over 3300 fps.
On the other side you never hear of excessive barrel wear even after thousands and thousands of rounds in more normal, still fast, chamberings such as 30-06, 270, 223, etc..
Of course barrel wear increases if you shoot repeatedly without letting your barrel cool.
So what is the "threshold" in velocity when your bore erosion increases significantly?? Around 3000-3300 fps for regular barrels short of exotic materials and treatment??
There is any significant difference in barrel wear, let's say between a 30-30 and the faster 30-06???
