I own on a variety of fiberglass stocks, primarily McMillan, though there is one Ramline in my collection.
Be careful when rasping.
Ramlines are not solid plastic - they're "glass-filled polycarbonate".
If you remove all the polycarb w/ the rasp [and it's not very thick - maybe .125"?] you'll be in 'soft' fiberglass, at which point re-creating a finished profile to match the lines of the stock will be more difficult - more like a body repair on a Corvette.
I'd call someone @ Ramline before you start removing material.
