[QUOTE="Bart B, post: 1125251, member: 5302"] [b]Typical .300 Win Mag Throat Erosion Rate[/b] With a given bullet jump distance to the rifling that's established as best starting out, note the bullet's jump distance to the rifling will increase .001" for every 10 to 15 rounds fired. All rifle throats advance with barrel wear, but I don't think one needs to chase the lands as they move forward. There's a few hundredths inch spread in bullet jump distance where accuracy changes very little, if at all. [/QUOTE]
