Bell and Carlson, Butler Creek, as well as HighTechSpecialies make models for the 1500 Howa. There are likely others.. These are what I found in the latest Brownells cataloge.. and are sybthetic and as drop in as any.. If you'd like to see how well the rifle works without the forearm pressure, simply insert a shim in the inletting to raise the action up a bit, removing the pressure. A piece of plastic such as a credit card cut up or simply a piece of light cardboard placed behind the front action screw will raise the action slightly and give an idea of what the rifle might do with a floated barrel. The same shim applied to the area just in front of the front receiver ring on the barrel reenforce will also work.. Just a question though, why did you use locktite on your action screws?
