Big beers, 10 gal mash tun

[ryanwms]

I started doing all-grain brewing about a month ago. I've done six batches and they've all come out pretty well.
I want to do an IPA or Barleywine next, so I'm looking at really doing a big batch.
My Mash Tun is a 10 gallon Rubbermaid cooler. The IPA recipe I have is 22 lbs in the grain bill, the Barleywine is 28 lbs.
Will my 10 gallon Tun be enough to do a beer this big?
If it isn't, what options do I have? How can i split up the water needs to make it work?
Thanks!

I do a Dogfish Head 90 minute clone in the same setup. For a 6 gal batch at 1.33 qts/lb, it's right at 7.5-8 gallons. I figured I could get about 30 lbs in if I made a stiff mash. My false bottom takes up the bottom gallon. Beersmith can tell you better based on you setup.

There's a decent chart in this thread ( https://www.homebrewtalk.com/f11/how-big-your-mash-tun-needs-123585/) which may help you

For a visual example of your Rubbermaid with a manifold, this is 26.75 lbs of grain at 1.1 qts/lb.
