I hadn't really considered the brass life aspects between the two. Less stretch is definitely a benefit.
How did you go about fireforming your cases, never had to do that in over 30 years of reloading.
Load the 280 brass shoot the 280 brass - bingo..
Save powder on the fire form by using the charge 10% higher than minimum at any bullet weight - I use 120's because I have a bunch , load the bullet into the lands... Shot away..
