What is max OAL in a AICS Long action

[backyardsniper]

I'm building a rifle in 300 ultra mag and I heard seekins bottom metal allowed for the longest oal. I went to thier website and it looks like tey use AI mags if this is the case I would just s soon put the gun in a AICS chasis. But I want to make sure that the mags wont restrict my oal too much if I wan to use the new berger 230 hybrids. I run AI mags in my 308 and I know they allow a littl eextra room, but what about the long action ones.
