Taliv,The 260 Super L/R has all those features if you want to use 308 Palma brass.

I like all 6.5mm cartridges,I shoot a 6.5 Creedmoor,260 Remington,6.5x6.8,and 6.5-06. I have a 260 AI barrel just waiting to go onto an action setting in the closet,as well as another 6.5 Creedmoor barrel.
While Hornady 6.5 Creedmoor brass has had primer pocket issues,the Nosler brass has been great.
I use resized 243 Winchester brass with my 260 since it is an AR platform that I use for hunting,and I don't care if I loose the brass in the field.
I have more brass issues out of my 6.5x6.8 wildcat than I've ever had with the Creedmoor. 6.8 SPC brass sucks!
I've got some Lapua 260 brass that I'll fire form in the 260 AI barrel,but I've never seen much advantage in their brass over other brands in the cartridges that I shoot.
I don't shoot factory ammo,so that's a moot point to me. People can argue which 6.5mm cartridge performs better,it all depends on what you want to obtain with your shooting.
