Follow up question, could I use both in an AR15 platform?
Both can be converted with some time & effort. Arguably the 6.5 Grendel is a fair bit less effort than converting 220 Russian.
Personally I shoot a 6.5 Grendel also so I prefer to keep that head stamp reserved for the original intent. I do not shoot 220 Russian so there is less chance for confusion with brass down the road. Thus I chose to go through the extra effort.
For what it is worth I have been using both Hornady 6mm Arc & the 220 Russian fire formed brass in bolt action rifles & both do very well as long as I am working w sane loads. Push the pressures a bit & Lapua will take a bit more abuse.
