Mule Deer:
Just out of curiosity, how much of a velocity difference did you find with the .280 AI over the standard .280?
I've only ever owned two rifles chambered for an "improved" cartridge. The first was a .218 Mashburn Bee, the second (which I still have) a .219 Improved Zipper. Both of the parent cartridges for those are quite tapered and the improved versions show a marked increase in case capacity.
I own a .280 (a Remington Model 725 - which I think to be perhaps the handsomest regular production rifle Remington ever produced, but that's just an opinion and worth whatever someone will pay for it) and I don't see that there's much room for increasing case capacity by blowing out a .280.
Thanks.
Rem
