In 280ai I have Redding, Hornady, and Lee dies.

It does not matter much, as I just use Nosler 280ai brass one time. So the dies just seat a bullet.

I have built 280ai rifles on actions:
a) 1924 VZ24 Mauser
b) 1980 Savage 110
c) 1949 Win M70 [killed a number of animals with this]

I have a 2018 factory Kimber 84L 280ai [killed a number of animals with this]
