Making a Overall Length Guage

How to make your own overall length guage on your reloading bench. What this does is allow you to take a empty cartridge case and make a OAL guage that is cheap and one that works. Once you take your initial measurement you should repeat the process three times to confirm the data you’re getting. Once you know the measurement set your seating depth deeper by .010″ initially. The reason is the seating die seats off the ogive. Bullet tips vary due to manufacturing process but the ogive is constant. Knowing this you’ll improve your accuracy potential conciderably. You can experiment to find the “sweet spot”. Once you find the best OAL write it down. If you’re like me you have several bullets that you use for different shooting scenarios.
