HTML5 & CSS3 Centering

Question

I am using the following HTML & CSS code excerpts. The "navmenu" items span the full width of the page in IE but leave space on the right side in Chrome. The full page can be see at www.bobabend.com. Can anyone tell me what to change so the "navmenu" items span the full width in both browsers?

.navmenu {
  padding: 0;
  display: block;
  z-index: 2;
  clear: none;
  margin-top: -13px;
  margin-left: auto;
  margin-right: auto;
}

.navmenu ul {
  padding: 0;
  background-color: #0000FF;
}

.navmenu li {
  padding: 0;
  list-style: none;
  position: relative;
  background-color: #006500;
  float: left;
  border: thick ridge #CC9900;
}

.navmenu ul li a {
  text-align: center;
  font-family: source-sans-pro, "Trebuchet MS", Verdana, Arial, sans-serif, helvetica;
  text-decoration: none;
  height: 45px;
  width: 200px;
  display: block;
  color: #FFF;
  text-shadow: 1px 1px 1px #000;
  font-size: medium;
  vertical-align: middle;
  line-height: 40px;
}

.navmenu ul ul {
  position: absolute;
  visibility: hidden;
  top: 32px;
}

.navmenu ul li:hover ul {
  visibility: visible;
}

.navmenu li:hover {
  background: #09F;
  z-index: 1;
  font-weight: bolder;
}

.navmenu ul li:hover ul li a:hover {
  background: #CCC;
  color: #000;
}

.navmenu a:hover {
  color: #000;
  font-weight: bolder;
}

.clearfloat {
  clear: both;
  margin: 0;
  padding: 0;
}

.wrapper {
  z-index: 1;
  width: 1050px;
  margin-left: auto;
  margin-right: auto;
}

<div class="wrapper">
  <div class="navmenu">
    <ul>
      <li><a class="long bold" href="Electrical Equipment Reliability 8-12-2014 Sec.pdf" target="_blank">Electronics<br>Reliability Paper</a>

Why not just put

.navmenu {
    padding: 0;
    z-index: 2;
    clear: none;
    margin-top: -13px;
    margin-left: 0;
    margin-right: 0;
}
