That pretty much sums it up, 16. The comparison for me is to other .473 LA selections. There isn't a lot to exploit--but it is there.
I do run my 7x57 warmer than 2750...:)
Mags are a different kettle of fish between my ears. A significant jump up in powder demands and recoil when loaded to their potential. A guy can easily build them as light as a 473. Did that once. Repented.
Have had a number of light 280AIs built over the years from a Forbes and RI on down but the Montana and factory brass is a lot less moolah and hoop jumping.
