260 AI rounds won't feed from AI AW 10rds mags, need help

[whiskeysierra762]

I was able to modify AI AW 10rd mags to work for my Sako 75 260rem. However, I had the rifle Ackley Improved and now the rounds seem to be binding on the shoulder of the case inside the magazines. The rounds still feed fine from the factory 5rd mags. Does anyone have any suggestions on how to modify the mags?

Secondly, does anyone know if there is another mag that is double stack, dual feed that is about the same size that I could also try? Or one that is double stack center feed that may work?

I have had a fairly busy history with the 260 Ackley.

Almost guaranteed issues with any double side feed system including internal box mags using integral feed rails in the receiver ala Rem700. Only truly reliable feed systems were mags that presented the cartridge in a single column / center feed orientation ala AICS 5 and 10rd.

The original AICS style magazines offer an almost controlled round feed aspect on all full length cartridges and are exceptionally reliable.

Terry, thank you for your reply. The article about your Tactical 260AI was a big influence on going to that cartridge.
