I picked up a 260 criterion with the longer match chamber. Does anyone have any data on OAL for 140 A-max and 140 hybrids with this barrel?

I will be blowing out the donor case for the Hornady gauge this weekend so I haven't measure yet. I'd like to order the bottom metal. Does the AICS mag allow you to seat on the lands with the hybrids?
 
Tag. I too have a Criterion Remage in 260 "Match". I spdidnt really know what was different about the match chamber. Sorry I don't have a modified case to measure the free ore of mine, but it shoots Berger 140 VLDs loaded to aics mag length really well
 
Does that leave you any room in your magazine?

AICS allow ~2.880" -- you can remove the front plate of mag to get ~2.980" but you will also likely have to notch the feed ramp on your action if stock Rem 700. That is my plan. You can also purchase Alpha 2 mags (Alpha Type 2 Magazine / AICS Short Action 308) but there are mixed reviews on feeding reliability and will still have same issue with Rem 700 feed ramp.
 
I have some Alpha IIs and they work great in my Savage action, Manners stock and CDI bottom metal. I can't remember how much extra room that gives me because I've went back to my old load where I don't need the extra room but I've been pleased with them. My new remage .260 will go in a AICS so I don't know yet if they will work in it.
