There are some subtle differences between the Hornady and RCBS versions of the adapter so if you do want to order one pleases do specify Hornady as opposed to RCBS as the two are not interchangeable.
Our original Beta tester told me:
I’ve spent a fair bit of time buggering about with the “hidden settings” on mine and have been quite happy with the results, …however, adding the “Thingy” definitely improves it whatever settings you use, for the average user it’s a great improvement especially if they’re using ball powders.


I have to point out we do not use the Hornady Lock-N-Load Auto Charge Powder Dispenser ourselves so have no direct experience of it however if the customer feedback is anything to go on the use of the Adapter tube/Thingy gives a significant improvement.
Price is exactly the same as the original RCBS version, they are in stock and are available on the Shooting SHED e-commerce site under the Powder Dispenser Tubes section.
