[QUOTE="B23, post: 430703, member: 13222"] Opinions will vary on this but here is mine. I have a 338-378 Accumark that currently, but not for long, has the factory 26in #3 barrel. Best so far has been 225&250 Accubonds w/Retumbo and 215's. When I even think about pushing either of these above about 3150fps my groups open up and look like a shotgun pattern. If I stay between 3050-3125 it will do 3/4-1MOA It is my opinion these factory light weight barrels are limited on how hard you push them. If you want to go 30inches I would go no less than a #7 barrel. Mine is not only getting a new Broughton 5C but it's also coming back as a 338 Lap imp. [/QUOTE]
