I used the M70 featherweight style for a 35 Whelen. This stock is too flimsy particularly in the foreend as delivered. I removed the foam from the foreend and laid in two layers of cloth and resin and refoamed it prior to bedding. It also required a lot of body filler in non-critical areas of strength just to fill the gaps. The nose of the comb was too high to allow bolt clearance so had to reshape that and lay new glass to replace the skin layer that had to be removed.
It turned out well but I bet I have more time in it than the manufacturer by far.
