I have been reloading for about 12 years now and for the most part I have followed the loading manuals to the letter with regard to COL. I have managed to develop some pretty nice loads for my rifles but I am wanting to start working with adjusting the bullet with regards to how far it sits fromth the lands. Now this leads me to my question, in reading some have suggested using a fire formed case from that particular gun, I understand why but others have stated they use a new resized case while other use something like Hornady sells which is a modified case, which is better, it may be obvious but I am curious, for those of you that work with adjusting the distance to the lands what is your preferred method?
Thanks

Get the Hornsby tool and it will make life a lot easier. It is not foolproof. If you have custom guns with tight chambers it can give bad information. You can send in fired, in sizes cases for that particular gun and they will prepare the case to use in the tool.
Been loading for 30+ years and this tool was a game changer when I bought it a few years ago.

I just use a cleaning rod. This is way easier and more consistent for me than trying to use Hornady's tool.
83% of all statistics are made up.

Mr.Clark I think your on the right path. Don't forget to measure bullet length before loading sometimes you'll get a short from shipping bouncing.
Only hits count.

As dave points out, the important measurement is to the ogive which is what actually engages the rifling. Depending on the tip of the bullet, you can have several thousandths variation in length, which is why it is most accurate to measure OAL to the ogive in terms of jump to the lands. When it comes to fitting in a magazine obviously its the total length of the cartridge. Yes. Always use a gauge to measure to the office of the bullet. Measurements to the bullet tip will vary a lot, several thousands of an inch, even with plastic tipped or hollow point bullets. Ogive measurements can also vary depending on QC at the factory. Worst bullets I've measured have been the nosler long range Accubonds. Ogive measurements varied by .008.

Thanks for the help. I learned early on to measure to the ogive instead of the tip. I was more curious as to whether it would be better to use a fired case or and unfired case, right now the consensus is to use a fire casing as it is fire formed to the chamber of that gun. I do not have a fired case for the gun I am wanting to measure so I will need to wait until the next range trip.

Hornady bullet depth gauge and modified cases.

In your quest to find the best bullet jump or jam, be sure that you don't jam the ogive into the rifling so much that if you go to extract a unfired round you pull the bullet out and spill powder all in your chamber. That really sucks when that happens...
I use the Hornady system and I love it. I also got myself a micrometer seater die You also really increase the pressure if you jam the bullet into the lands. Always start loads low when on the lands.

I have the Hornady setup as well and it works great. You can send them a fired case and they'll thread it for you so you're absolutely tooled up for that specific weapon.
I firmly believe that a double gallows should be constructed on the East Lawn of The White House. Politicians who willfully and shamelessly violate their oath to uphold and defend the Constitution of the United States of America should be swiftly tried and, upon conviction, publicly hanged at sunup the day after conviction. If multiple convicts are to be hanged they can choose with whom to share the gallows or names shall be drawn from the hangman's hat to be hanged 2 at a time.
