While there are still Type 1 bolts and barrels floating around out there, it’s really uncommon to come across one.īear Creek Arsenal exclusively uses the Type 2 6.5 Grendel barrels and bolts. This is awesome for us shooters since the Type 2 Grendel is the better, stronger, version. This has led people to think that maybe Type 1 is the OG… it isn’t.Įventually, Alexander Arms got their head on straight and submitted 6.5 Grendel to SAAMI for approval and in doing so released their trademarks/copyrights. To get around this, Les Baer slightly modified the barrel and bolts they sold so that they were not the exact same as the Grendel specs.Īnd then for reasons that I honestly don’t understand, the Les Baer version started to be called “Type 1” while the Alexander Arms version was called “Type 2”. Part of that process requires that you release any copyrights and trademarks to the ammo and chamber design.īill Alexander didn’t do that (at the time) and chose to keep his copyright on the 6.5 Grendel. Normally, when a new cartridge is invented (and you actually want anyone to use it) you submit the specs to SAAMI (the industry organization that standardized ammo and chamber specs) for approval and standardization. While the cartridge is awesome, the story gets a little… weird after that. I always enjoy talking about this cartridge because it lets me say that it was invented by Bill Alexander of Alexander Arms and it was named after the monster that attacks Beowulf’s mead hall in the poem Beowulf. Two that came pretty close are 6.5 Grendel and 6.8 SPC. There have been a dozen or more attempts to solve this with a new cartridge, but few have come close to succeeding. There are a lot of bad guys in the world who aren’t with us anymore proving the effectiveness of that little round.īut even on its best days, 5.56 NATO is a bit lacking when it comes to raw energy. Don’t get me wrong, 5.56 NATO is a great cartridge and it covers a lot of ground. 223/5.56 NATO cartridges were invented, people have been trying to replace them.

With so much in common, it’s no wonder that you may not be sure what is right for you.įrom the history of the cartridge to the ballistics, we’ve got all the information that you need!Įver since the. 6.8 SPC Head to Head: Which is Better?Ħ.8 SPC and 6.5 Grendel have been rivals since they hit the market. 350 LegendĬalibers with a bullet diameter of 0.458' or less.
