Which still makes me wonder how/why we see the 280 AI vels that get posted on here and on Noslers own website.



A bit more capacity for the 280AI,and loading to 65,000 psi . Plus 26" barrel IIRC, don't have the manual in front of me...... Little things add up.




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
