Bob,
Doc has it in the right perspective. It's another neat cartridge. I have been playing with both the 280AI and 7RM as mentioned in my previous post and am finding that since the 7 Mag is throated deep it looks like a guy might get all the 7828 in the case it will hold and still allow a bullet to seat without too much pressure or at least no mechanical signs of too much.. I can do that with the 280AI but it won't hold much over 64gr of powder with a 140 in it and the 7 seated long for the deep throat will hold mid 70's and it looks like 3400 fps is a real possibility with a 140. Like you mentioned 7 Weatherby velocities if the chamber and throat are right which for me is a pleasant surprise.
I like the 280AI in the NULA. Chambers a round well and shoots very accurate and it's another neat cartridge. Hope to get out if it's not too hot tomorrow and ring both of them out a little more.
Dave
