AOL Guage

[Remshooter]

What is the best measuring tool/gadget available to measure AOL from cartridge base to Ogive of bullet??

In my opinion that would be the Hornady Lock n Load OAL guage. There is a review here...

+1 on the Hornady Lock-N-Load, been using this system for years, mine was the Stoney Point. Simple, repeatable and it works. Also have a Sinclair, it works fine, just a little more complicated to use.

Thanks for the info, will check out the Hornady and Sinclair.

Not sure exactly what your wanting to measure. If you want to find out where your bullet will touch the lands then you want a Hornady OAL gauge.

If you are wanting to set up your seating die to have all bullets measure the same to the ogive then you need a bullet comparator.

Hornady and Sinclair both make Comparator Bodies, and inserts from both will fit either. Hornadys inserts are aluminum where the Sinclairs are SS. Either body is fine but I think you will like the SS inserts better.

Actually I need to do both types of measurements, but primarily looking for an accurate way to measure bullets after setting up the seating die. On finding out the bullet length where it touches the lands, I have always used a fireformed case with bullet loosely seated, close bolt , remove bullet and measure length to get a reference dimension. Is this an acceptable method??

Works for me. You will want to try it 4 or 5 times to make sure you are getting a consistent reading.

Mhouser,
I have used the method you are talking about for years the problem with it is if the bullet doesn't move when opening the bolt, is actually jammed quite a bit not just touching like you would think. I found this out after purchasing the Hornady oal tool. I give a plus one for the hornady tool. I read the review that was posted and disagree with there method of tapping on the gray rod, I tried that when I first bought it and found that actually jammed the bullet quite a bit, I rotate the tool to make sure the shoulder is fully seated into the chamber then just push the bullet in to touch the lands. Larry Willis makes a nice comparator tool which is very nice, I sure like mine especially for setting up my sizing die for shoulder bump, you might want to check it out. Good luck to you. http://www.larrywillis.com/
