[QUOTE="woods, post: 332642, member: 6042"] I have tried all the methods and have the following observations: 1. Splitting a sized case neck or slightly bending the neck of an unsized one where the bullet will slide in and out but with some tension was inconsistant for me. It was either the lands holding on to the bullet and pulling it slightly back out or the leade permitting a different depth due to very slight obstructions or the bullet being out of alignment. For gross measurements this will work if you throw out the out of line lows and highs and just take an average and are loading .050" off then you are close to OK 2. Using a cleaning rod where you insert the cleaning rod down to the bolt face (make sure the firing pin is retracted) and mark it and then insert and hold the bullet against the lands with a pencil or wooden dowel, and insert the cleaning rod down to the bullet tip, mark it and measure between the marks. Also inconsistant with the possible reasons being the inaccuracy of marking exactly at the muzzle [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN0657.jpg[/IMG] or the inaccuracy of measuring to the .001" between the marks [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN0662-1.jpg[/IMG] 3. The Hornady LNL OAL Gauge is an excellent tool but it takes some practice and some give up before you learn how to get the same results everytime. It uses a modified case where the bullet slips in and out and a rod that goes through the center and pushes the bullet to the lands insert the bullet keeping it back in the case [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/300wm3.jpg[/IMG] put the case in the chamber and push the rod in to push the bullet against the lands [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSCN0525.jpg[/IMG] measure either to the tip of the bullet or with a comparator [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN0037.jpg[/IMG] With some practice you can come up with the same measurements everytime. It depends upon the consistancy of the force you push the bullet against the lands. But, you need to allow for the headspace or head clearance of the modified case unless you drill and tap your own cases that fit your chamber. 4. The Sinclair OAL Gauge [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN0425.jpg[/IMG] only fit some of my guns and the knurl knob was extremely hard to tighten down enough to keep it in place on the rod, even made my own slot for a screwdriver but eventually gave up on it. The best way I have found I will show you in the next post since there is a limit of 6 pics per post [/QUOTE]
