Gauges\" class=\"clickTracking\" campaign=\"hornady-facebook\" target=\"_new\">https:\/\/www.facebook.com\/hornady<\/a><\/p>\n<p>Obsession with accuracy drives you to think up some  interesting ideas, one of those is Cartridge Overall Length.\u00a0\u00a0 It is based on the premise that when a  bullet is fired from its cartridge case before it engages the rifling, it is  inherently unstable, and that in this \u201cfreebore,\u201d the bullet can get  cockeyed.\u00a0 When you remove as much of  that jump as possible by seating the bullet closer to the rifling, it will  eliminate this chaotic \u201cfreebore\u201d and hit the rifling straighter and more  consistently. <\/p>\n<p>The careful hand-loader or re-loader will try to minimize  that jump to the rifling as much as possible. <\/p>\n<p>To measure this distance by hand, you have too loose fit a  bullet into an empty cartridge case and seat the cartridge in the chamber,  starting with the bullet out too far, so it touches the rifling and moves back  into the case as you insert the cartridge.\u00a0 <\/p>\n<p>I&#8217;ve tried to do it without this tool from Hornady and it is  very difficult to get the bullet to be loose enough to go back and forth, and  stay put after you press it against the rifling and remove it. <\/p>\n<p>With a lead bullet especially, what you find is that the  rifling marks the bullet and sticks to it so when you pull it out, the  measurement is off.\u00a0 I&#8217;ve even\u00a0 traveled to the range with 20 rounds of 45-70  seated to what I proudly thought was 20 thousandths off the rifling, only to  find that the rounds I made didn&#8217;t fit in the chamber because the bullet had  stuck to the rifling when I pulled it out. <\/p>\n<p>That is why Hornady made these Cartridge Overall Length  Gauge tools.\u00a0 There is a straight one for  bolt rifles and other types of actions where you can access the rear of the  breech in a straight line, and a curved one for lever action guns and others  types of actions where you can&#8217;t. <\/p>\n<p>You should note that a loaded cartridge that has been made  with the bullet as close to the rifling as possible, or as we say, at the  longest \u201ccartridge overall length\u201d that the rifle will tolerate, often will not  feed reliably from a magazine.\u00a0 When you  load to maximum overall cartridge length, you should assume that you will be  loading cartridges into the rifle one at a time. <\/p>\n<h2>Measuring Maximum Cartridge Overall Length<\/h2>\n<p>You will need both the gauge itself and a modified cartridge  for the rifle you want to measure. You can&#8217;t use a regular empty cartridge  because it has to be drilled and threaded for the tool.\u00a0 You can order these special cases directly  from Hornady or on Midway, along with the tool itself.\u00a0 The pictures are of the 45-70 case I have  used with the straight version of this tool for many years in my Sharps and  Hi-Wall rifles. <\/p>\n<p>The modified cartridge case screws onto the tool and you  insert the cartridge into the breech. On a bolt action rifle that means you  must remove the bolt, and on a rifle like the Pedersoli Sharps you see here,  you just drop the block and insert the case.<\/p>\n<p>Then you fish a cleaning rod in from the front of the muzzle  to push on the front of the bullet to act as a counter pressure to the rod in  the tool. With the two rods in hand and the bullet in the middle, you can feel  for where the rifling begins. Then you lock the tool, and when you remove it,  even if the bullet stuck to the rifling a little on the way out, you can put  the bullet back to where the tool measured that first touch. <\/p>\n<p>Hornady recommends that you seat your bullets 20 to 40  thousandths off the rifling but many people, especially in the black powder  world where pressures are not as much of an issue, seat them even closer.\u00a0 Seating directly against the rifling, without  any jump from the cartridge case, can lead to large pressure and velocity  differences, and with modern smokeless powder it can lead to unsafe pressures,  especially if you are already at the top of recommended loads.<\/p>\n<p>After you have measured, you will then set your seating die  so that the measurement on your finished cartridges matches the modified test  cartridge, or is 20 or so thousandths less.\u00a0  If you are a serious hand loader, I suggest that you get a competition  micrometer seating die made by Redding. <\/p>\n<p>I have never used the <a href=\"https:\/\/www.hornady.com\/store\/Bullet-Comparator-Kits\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"the-hornady-lock-n-load-cartridge-overall-length-oal-gauges\" title=\"The Hornady Lock-N-Load Cartridge Overall Length (O.A.L.) Gauges\" class=\"clickTracking\" campaign=\"hornady-bullet-tool\" target=\"_new\">bullet  comparator tool<\/a> that Hornady recommends you take measurements with  instead of measuring off of the top of the bullet as you see here. The bullet  comparator is a sleeve that has insert rings. When you slide the comparator and  the right size ring over your bullet, it catches on the ogive, which is where  the bullet turns inward from its main body to the point. Hornady makes bullets,  so if they say that the ogive is a more reliable measurement indicator, I  believe them, but I have never tried it. The ogive of course is what touches  the rifling, not the tip, so that is what you are measuring with the overall  cartridge length tool. Apples to apples, you probably would want to get the  comparator.<\/p>\n<h2>Throat Erosion<\/h2>\n<p>The Hornady Overall Cartridge Length tool is also the only  accurate way to measure throat erosion on your rifle. This can be a serious  issue for competitive shooters who fire tens of thousands of rounds per  year.\u00a0 Sometimes you find that a rifle  that used to shoot great all of a sudden goes south on you with the same  ammunition loaded the same way, and there is no outward explanation for it at  all. <\/p>\n<p>The controlled burn that happens when you fire a cartridge  releases hot, pressurized gas. This, combined with a constant battering of lead  or copper jacket, can and does damage the forcing cone inside your rifle  chamber, and especially the ridges of rifling that stick up above the surface.  Over time these ridges wear down.\u00a0 The  result is that the bullet must travel farther to get to the rifling, and this  can lead to a drop in accuracy because the bullet has too much time to get  cockeyed before it engages.\u00a0 <\/p>\n<p>This tool allows you to stay on top of your throat erosion  by measuring it from time to time. If you find that the bullet engaging the  rifling 20 thousands over what it used to, you can try loading the bullet in  that much longer to see if you get back the accuracy you expect from the gun. <\/p>\n<p>The careful hand-loader deals with a lot of variables in the  quest for ultimate accuracy. Overall cartridge length, or what this really is,  overall distance from the case head to the ogive, is an easy variable to  measure, control and repeat.\u00a0 What bullet  the gun likes, or what velocity it likes with its favorite bullet, can be  agonizing to figure out, but maximum overall cartridge length is easy with this  handy tool from Hornady. <\/p>\n<p><strong>Direct from Hornady:<\/strong><br \/>\n  <a href=\"https:\/\/www.hornady.com\/store\/OAL-Gauges-and-Modified-Cases\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"the-hornady-lock-n-load-cartridge-overall-length-oal-gauges\" title=\"The Hornady Lock-N-Load Cartridge Overall Length (O.A.L.)
