6,5 Grendel a barrel burner? No - Varoum - 02-14-2012 According to this link, it is not a barrel burner. http://bulletin.accurateshooter.com/2011/04/overbore-cartridges-a-working-definition/ 6,5 Grendel a barrel burner? No - mlmiller1 - 02-14-2012 That is a very interesting "quick read" article. I wonder if the conclusions are valid? I suspect the 6.5 grendel is not a barrel burner but I suspect that due to the fact velocities are quite a bit lower & powder charges quite a bit less than say a .260. If this graph has any validity, it could be very useful to anyone considering or comparing a particular caliber or calibers. Thanks for posting that link! MLM 6,5 Grendel a barrel burner? No - bwaites - 02-14-2012 Define "barrel burner"? My definition is a cartridge which shows significant degradation in accuracy at less than 2000 rounds. My WSM 7mm, for instance, qualifies. But the Grendel? Not even close! I went almost 6000 rounds before I saw the Grendel drop off in accuracy, and it was still sub MOA at that point. I just couldn't shoot .25 MOA groups with it anymore. It's a relatively low pressure round, so that helps, too. You want to see a really low number, look at the Beowulf! It's index is like 178! |
