AICS magazine experts

[Fjold]

I bought an Ultradyne chassis for my Savage short action, 22.250AI and it takes AICS magazines,

I looked on PMags site and they recommend using the 7.62 magazine for the 22.250 but downloading it to 6 rounds because of the taper of the 22.250 cartridge case.

Another company makes an AICS magazine specifically for the 22.250 but I'm afraid that because I'm shooting the Ackley Improved case without the taper that it won't feed correctly.

What do the experts recommend for the 22.250 Ackley Improved case, the 7.62 mags or the 22.250 mags?

I went and measured my 22-250 ai reamer at the shoulder and I got 0.457" diameter.
I grabbed a 308 reamer and I got 0.456" at the shoulder.
I don't think you need anything other than a standard 308 magazine.
6.5 Creedmoor measures 0.460" at the shoulder and feed perfectly fine out of 308 mags.

The PMag AICS short magazine for the 7.62 works perfectly. There is more room in front of the bullet than I like when loaded into the magazine but it feeds flawlessly so far.
