Thanks for the info!PO Ackley did a bunch of testing in the 50's-60s with wildcats by reaming chambers such that the shoulder was moved forward and the angle changed to allow more powder and hence more velocity.
In most cases, you simply fire-form the brass in your AI chamber using the parent cartridge. In some cases, you can purchase brass with the xxx AI headstamp.
This was very successful and popular with some cartridges to the extent that we now have factory rifles and ammo for ones like the 280AI.
In other cartridges, the difference was minimal.
Lots of info if you google it...

But what i guess im wondering is I have a .243 and if i get .243 AI rounds, can they be shot from my normal .243??
no you wont even get the bolt closed
lol yea that tooSavage88,
Even if you can, why would you want to do that ... defeats the purpose of fireforming it into an AI ??? lightbulblightbulblightbulblightbulb

Why wouldn't it be? 30-06 AI and 280AI are great chamberings, I would think a 270 AI would be no less.Even if you can, why would you want to do that ... defeats the purpose of fireforming it into an AI ??? lightbulblightbulblightbulblightbulb
ADDED:
Don't let Ackley's research 50+ years ago stop you from venturing out of the norm. There's been lots of technological advancement since then; powder, primers, bullets, barrels, etc ...
I personally am finalizing a .270 AI because the naysayers said it is not worth it ... that should stir up the pot.

It just doesnt make sense to me. From what ive researched, the gains are not that outstanding. It would make sense, if it was a small improvement to the cartridge to gain that little bit extra emfff without gettin a whole new rig. But having to buy a completely new rifle to get minimal increased performance doesnt seem worth it to me. Buying a larger or more powerful caliber makes more sense to me.
Please correct me if im wrong. Im curious!!!
