[QUOTE="Engineering101, post: 964899, member: 63138"] Have you guys seen the chart that estimates how overbore a cartridge is over on accurate shooter.com? [URL="http://www.accurateshooter.com/technical-articles/overbore-cartridges-defined-by-formula/"]“Overbore” Cartridges Defined by Formula within AccurateShooter.com[/URL] I have a 26 Nosler down at the gunsmith getting put together right now and with all the overbore talk I thought I would try to quantify how overbore it is. Some comparisons NOT on the chart: 338 RUM = 1,255 7mm WSM = 1,298 300 RUM = 1,578 7mm RUM = 1,789 26 Nosler = 1,852 Looks like the Nosler is the winner but only by about 3.5% over the 7mm RUM and 17% over the 300 RUM so it is not like it is completely insane. So there you go, the 26 Nosler should be about like the 7mm RUM for barrel life. What kind of barrel life are people getting from their 7mm RUMs? [/QUOTE]
