Federal, &amp;nbsp;having a good reputation doesn&#39;t want negative feedback, &amp;nbsp;I am glad that they are not quoting the ballistics from the typical bolt action rifle and the normal 22-24&amp;quot; tubes like was the previous practice before the chronograph became affordable to the average American reloader. As for the 55gr rounds, &amp;nbsp;I am assuming that since the typical 1in12&amp;quot; twist usually found in many bolt action varmint rifles is more than adequate to stabilize the bullet weight, ballistics are taken from the longer bbl. on most of these rifles hence the reason for the much higher velocity and fpe, not to mention that the heavy bullet can&#39;t be driven to the same velocity due to the increased pressure involved. . Long answer but I hope it helps! !?&amp;nbsp; <div class="bvseo-author">Answered by: rgr41mag</div> <div class="bvseo-pubdate">Date published: 2017-12-02</div> </div> </div> <div class="bvseo-question-answer" data-questionid="1438056"> <h2 class="bvseo-question"> The title of this product reads Federal HST, but the picture shows Federal Fusion MSR.
