Hornady® Lock-n-Load® "A" Series Modified Cases are specially modified to work with Lock-N-Load Precision gauges. To ensure that they remain perfectly square for precise alignment in the chamber of your firearm, a special fine thread is used to attach them to the gauges. In addition, the neck of the case is made perfectly round and then opened slightly to allow a standard diameter bullet to slip into the case mouth effortlessly, but concentrically, to ensure the most precise results possible. Made in USA.

AccurateAccurate when used correctly but be careful. If the setscrew on the collar is not tight (mine was loose when first used) the measurements become meaningless.
This device and any similar will require much finesse to use correctly. One should carefully make about 100 measurements and enter them into a spreadsheet. Sort them by size, discard those that are unrealistic from the high and low values. Then average the remaining.
While the enclosed instructions are useful they need to be considered in conjunction with watch how-to videos for this device from YouTube.
And BTW - don't use it without the associated Hornady micrometer attachments...

20+ years of using this systemStarted using this measuring system when it was with Stoney Point and continued with Hornady. Works perfect in all my rifles. The modified case MUST be used with the OAL gauge in order to work properly so I am not sure why anyone is putting it in a rifle and closing a bolt on them. They are not designed to be used that way. Thread them onto the OAL gauge, insert bullet into neck of case, place OAL and modified case into chamber until modified case shoulder is snug in chamber, tighten down the adjuster on the OAL gauge, remove and measure the Max OAL length either to end of bullet or use their ogive measurement system to get the absolute most accurate bullet MAX OAL. Using the modified case without the gauge is defeating the purpose and accuracy potential of the system. Pretty fool proof system when used properly. The repeatability is also very good. Highly recommend.

Modified Cases For Hornady OAL Gauges Are GreatI have tried the "do it yourself" methods of measuring overall length, but I always had doubts about the accuracy of the measurements. So, I invested in an overall gauge and a modified case by Hornady and compared my DIY measurements to the measurements I got using the gauge and modified case. Needless to say, I have been happy with my purchase.

Too BigPurchased the straight gauge with the .204 Ruger modified case.
The gauge rod was too tight in the metal barrel and couldn't move easily without shaving off moulding lines.
The .204 Ruger modified case would not hold any bullets, the neck was too big, the bullets fell right into the case. Not sure if the modified case can be sized to work properly. It would be trial and error to get the tension right.
The system was inoperable as shipped.

Great productThis O.A.L gauge is a great tool for any reloaded. It is an easy way to evaluate throat wear, and measure proper bullet seating length. I would not be without it!
Thank you for your question. The Hornady Lock-n-Load A Series Modified Cases are sold by the single case for use with a Lock-N-Load (OAL) gauge for obtaining an accurate measurement.

I can't find a Hornady modified case for a 7mm08 Remington, 7mm Remington mag, or the 300RUM to measure the overall length
Asked by: Garey
What's the difference between A series and B series for the modified case?
Asked by: MBATES
Thanks for your question! Each series fits a different set of firearms.
