[QUOTE="codyadams, post: 2388947, member: 87243"] The guy is asking about building a hot rod to run with N570, so barrel life probably isn't that big of a consideration ha ha. However, it really goes without saying that burning 120ish grains of powder down a .338 bore, especially a powder like N570, running it on the higher side of pressure, isn't exactly going to yield good barrel life. With cartridges like this, we're here for a good time, not a long time ha ha. A 33XC will have around 250 fps +- over a .338 NMI with same length barrel, same powder, running similar pressures, and using same bullet weight. Whether the 250 fps is worth the 20-30 grains of powder increase will be up to each individual person. Barrel life will depend greatly on how high of pressure you load it, if you shoot strings or allow the barrel to cool, and powder used. [/QUOTE]
