[QUOTE="J E Custom, post: 1153618, member: 2736"] The best way to get this dimension is by using a Cartridge Overall length Gauge. [url=http://www.midwayusa.com/case-gages-and-bullet-comparators/br?cid=8868]Case Gages & Bullet Comparators- MidwayUSA[/url] They are very cheep and can be a very useful tool that works on all bullet designs. To set your dies = I like to use a full length sized (Un Primed) case and take the bullet you intend to use, seat it shallow with the dies backed off. then using the COAL gauge or the chamber its self, start chambering the round by cranking down on the die 1/2 turn at a time until the bolt closes easy (Don't force the bolt to close or you will get a false reading and possibly stick the bullet in the bore). Normally when done this way the bullet will engrave 4 or 5 thousandths so you have to tighten down on the dies just a little more. This is where the gauge comes in handy for precise measurements. Lead tipped bullets can be very accurate if they are handled carefully. Most big magnums like some free bore (It helps keep the pressure down) I normally just use the magazine length - .020 to .030 to start with, some bullets will like .090 to a .100 off the lands and the gauge will tell you where you are when you find the most accurate load. These tools are made out of aluminum, Plastic and brass so they will not damage the bore or the chamber. J E CUSTOM [/QUOTE]
