How much malt have you successfully mashed in a ten gal cooler? I am planning a Wee Heavy and am worried about space. Maybe just do two mashes?
I think I've seen it posted that you can do the bigger beers in a 10G, but with not much room to spare.
I'm sure someone else will chime in....
Drinking: All kinds of stuff
Kegged: Rollings Hills Pale Ale
Conditioning/bottled: Rollings Hills Pale Ale, Clackmananshire Wee Heavy
On Deck: Oldenwald Dunkelweizen.
at 1.25 qt/lb my 5 gal round cooler maxed out at 12 lbs of grain.
I upgraded to a 10 gal cooler, and haven't maxed it out yet, but I would venture at same thickness, probably around 24 - 25 lbs

Those calculators are great, but don't forget that you need to leave room in the tun to sparge it.
i've pushed it and done 30 lbs. (not sure what the water to grain ratio is there). i only got about 65% efficiency though, and it was full to the brim which made sparging awkward.
26 lbs. is about as high as i'd go now.
i just doughed in a 10 g batch of spiced pumpkin ale in my 10 g igloo cooler with a false bottom. there's 26 lbs of grain and pumpkin, 6.75 g of water (1:1 ratio), and a little room to spare.
