[QUOTE="Bob Wright, post: 1872785, member: 104363"] By contrast, my load workup in a custom 280AI found brass pressure at 59.0 gr of RE23, 3168 FPS and using a 143 Hammer Hunter. I had a guy run quickload with this and using a 145 Barnes (no Hammer bullet data in QL). From his note to me about quickload: "I just checked the numbers with it and you should be in a node around 59.0gr at 61,200psi and a MV of around 3034fps with 104% case fill and 97.33% powder burned." So, in a general sense, I will be probably find a node about 57.5-58.0 grains averaging 3090 fps with a 143 Hammer and just under 61.2K psi, since I actually hit pressure at Quickloads 59.0 suggestion. With Nosler brass, my experience is, a sticky bolt is also a primer pocket loss. Guaranteed. Since loading data generally is hit and miss on this cartridge, Quickload is the one the OP should be looking at for a 65Kpsi max pressure rating for this cartridge. I'd say you're well over it.
