Besides not wanting to get into another cartridge, the two things that have held me back from 6.5 Grendel are the lack of good standard capacity magazines and the thin walls of the bolt on an AR chambered in it.The magazine issue does leave me a bit irked.. lets hope that Magpul gets on the Schick with it.
Which is a shame because I think it is a fantastic cartridge. The steel cased ammo availability is huge, and its ability to perform well from a 12" barrel all the way up to a 24" barrel is really cool.
