Soggy bottoms?

I'm not sure baking blind will solve a meaty pie with gravy soggy bottom problem, the gravy will always soak into the pastry. Baking blind is usually for sweet stuff like tarts or quiches. You could reduce the gravy content of your filling or put your pie in the oven on a very hot pre-heated baking tray to give it that bit of extra opportunity to cook the bottom. I may be wrong as I very seldom do a pie.
