Regarding the group buy...possibly! Just checking back here because I started a new job (as in house counsel at a very large company in my industry...raise...benefits...YAY!!) and have been crazy busy, so I haven't made it out to pick up any large quantities. My buddy is great, so we'll see

[for brevity]
That's good news all around MeyerLemon.
IF [the biggest impediment/word in the English language] the group buy comes to be do let me know?
As to specific items I would order ... whatever the group decides is good for me. I'm looking for the best price on popular ammo mostly, as a "savings account" of sorts, but would have a personal use for .308/762x51. [308 NATO]

Always keeping in mind that Rockefeller is NOT my familial name. ]
The shipping and handling after the sale May make my contribution pretty small all things considered.
IF it comes to pass you can contact me here or through one of the admins here.
stay safe,
