It's not a very standard practice, that's all I see. It might make a manual inspection of hour site more likely. And also I don't see any advantage for you in using a 301. Why not just have a anchor tag point directly to its destination page and use rel="nofollow" to keep all PR on your site? The 301 will mean less PR for your own urls.
