Does anyone use this and a false bottom for a mash tun? f so, what is your dead space? I just replaced my Rubbermaid cooler and transferred over all of the existing hardware including the false bottom. I had 0.41 gallons of dead space in the Rubbermaid.
FWIW, I don't measure deadspace. I feel like the cooler needs to be warmed up before using, so I run 4 gallons or so through the system first. I heat to 160 in the HLT, transfer, and then let it sit in the Rubbermade for at least 20 minutes before using. By doing so, the deadspace measurement really doesn't matter as it's added in to both tanks by then. I use a weight to hold the Rubbermaid lid on tight and am able to keep the mash temps of 148 to 154 within a degree for a full hour long mash. I'm using a bazooka screen (not that it matters), and also tip the mash tun and give it plenty of time to drain.
Hope it helps.
