I have 5 EH-1 stocks that have 3-B barrels on them. I am considering a 2-B build also. I think, with a proper inlet, that it would be fine.
It will work, but will look funny. Another stock with that shape and smaller forend is the Mcm game scout.
Look at the ag composites alpine stock, very similar to the eh1 but cheaper, and has a higher comb. Shot my friends 28 nosler with one, very comfortable and great cheek weld even with 56mm obj. He used a fluted 3b.
thanks they look goodOh, that (http://agcomposites.com/rifle-alpine-hunter/) does look nice!
