Not Howas, but IIRC they were designed for Nosler by the guy that designed Howa's action. There would be some similarity. Here's a link that has a picture depicting the differences.

For some reason some on here are against the Nosler rifles, but they are a trued action, custom barrel, Cerakoted, and shoot well. IMHO I'll echo if you can handle both that would probably make the decision for you.
