I'm glad Peterson is making some of the Weatherby Cartridges. I just got 100 pieces of 6.5x300 peterson brass a few days ago.

I have a 6.5 CM that puts them in under a half inch consistently and better when the nut behind the barrel does his job. George Muska made my first custom rifle way back in the 80's it was a 280 express and it was a tack driver. So with that memory I have decided to try the 280 again but have had no dealing with the AI I figured I would pick the collective brains on here By The Way thanks to all that have answered and given input it is appreciated.

I have 308, 300 WM, and even a 338 lapua mag. Soooooo I thought back to earlier times and want to revisit the 280 world but had no experience with the AI.
This boils down to personal preference, and you must decide which route to take for your intended purpose. I prefer .30 cal (.30 Lara, 3 .300 WM, 2 .300 WSM, .30 Gibbs, 2 .30-06, .308 Win, 2 7.62x39, a .30 M1) over .28 cal. In 2012, I was going to build myself a .280 AI but went with a .270 AI instead because the body in their brother has one.
Ackley's improved cartridges serve two purposes: increasing case capacity and reducing case stretching. The latter is often not realized by the average end-user. Good luck!
Take a look at the 284 or 284 Shehane. Very proven cartridge for target/hunting applications and a very decent barrel life. The 284 is pretty much plug and play....the improved version Shehane....shoots small fire forming with H4831sc and Berger 180's.
whats tour thought on the barrel length and caliber do you have in mind
My initial thought was always "how well does it currently shoot"? The 30-06 won 1000 yard shooting matches for years. It certainly bucks wind better than some smaller calibers. What is the concentricity of your barrel? Ackley talked me out of a barrel change as my Rem 700 barrel was one of the most concentric he had measured. 30-06AI would boost your velocity slightly and be fun to play with. You'd get more reloading for sure.
My 1959 Browning FN Safari 30-06 shoots sub-1/2"MOA with 180gr NABs. I'd never change it!

I think the .30-06 would still win big matches, but... there aren't enough of the high-end shooters shooting it anymore, there are just too many other calibers to play with these days. .30-06 Springfield with a 180gr/190gr or 200gr match bullet at somewhere around 2700 to 2850 fps is still pretty formidable on the competition range in the LR game. The winner circle calibers are, really... a matter of mathematics, the numbers... the more one caliber is used (for whatever reason) the more it shows up in the winner's circle. Just my 0.2 Cheers
