244AIin short chambered 243 Barrel-Any EXPERIENCE here

Anyone finish chambered a new 243 Win short chambered barrel to 244AI?
Push come to shove can turn one thread off barrel etc but would prefer to us barrel as is.
My analysis shows 244AI will remove 243 chamber with a very small buffer.
Appreciate comments from those who may have performed this chambering.
Thanks.

Don’t have a drawing of a 244 AI but it should work fine. As long as the case body diameter is larger than a 243 at the same depth into the chamber. That sounds like a good 6 mm cartridge !
