I know this is like a member of AA going to a bar asking for advice on party drinks. ;)but I need guidance on whether to purchase a CZ-527 6.5 Grendel. Intended use would be shooting at the range and W/T deer at ranges less than 100 yards but (and here comes the muddying of the water) I already have the Carbine in 7.62x39 which has proven to be a 1 MOA shooter. Plus it is very handy for carrying through dense underbrush where I hunt and I have a vast supply of components for the 7.62 shortski.
Has anyone ever seen or used both cartridges on deer and could you see one being superior over the other?

Shew me thy ways, O LORD: teach me thy paths.
