These nitrided expander mandrels are great.

Quality product ! Works perfectly as it was designed to do,

Yes, I would recommend to a friend
Great upgrade
I can always count quality. The TiN coating makes neck expansion easier and more reliable than just lubing the neck.
Must have to reload
Gives consistent neck tension on your reloads. The consistent tension will improve groups
Precision Product
I am not sure why the standard die set doesn't come with an expander mandrel. I.M.O. The regular expander ball (even in expensive die sets) is not the best way to resize without stretching the brass cases. This is a great product that is precisely manufactured - I am glad that I finally found it!
Does what was needed. as described
Fast and accurate way to set neck tension. Can't find anything bad about it.

Right size works well be careful get adjusted not crush case mouth
Much more consistent
Picked up the Mandrel to help with neck tension. While seating bullets, I could feel that every few cases there was more "resistance" therefore most likely more neck tension. After using the mandrel each case felt pretty much like the next while bullet seating. Next is to get out to the range and see if it's made a difference.
More uniform neck tension
The quality seems first-rate and there is nothing to adjust. You must also buy the holder die to be able to use it. It is quick and easy to swap mandrels. I have been reading Top-Grade Ammo by Glen Zediker and he recommends using a mandrel. It appears to solve my problem with non-uniform neck tensions. I first lube and full length size the cases which tends to produce tight necks which are not very uniform. Next I length trim and bevel the necks, if needed. Then I use the mandrel to expand the necks sightly and center the inside diameters. (Then you must decide if the outside necks are sufficiently uniform or outside neck turning ((or sorting of the cases)) is required. This requires more tools but I believe there is still a benefit even if you don't do it.) I have loaded about 100 rounds since receiving this tool and the bullet seating forces seem much more uniform and smoother but still adequate for bullet retention. My bullets are coated with boron nitride and I don't use any other lubricant when seating them. I am not equipped to measure the seating force but subjectively it feels much better. I am lubing every 5th case inside neck with Hornady case lube when I use the mandrel. Then I soak all of the cases in denatured alcohol to remove the lube from the inside and outside of the cases. The mandrel diameter is still in spec but I am wondering how long it will last. If it wears quickly I will spring for the carbide version. This is a lot of effort, but I am trying to produce the best loads I can for shooting at 600 yards in high power matches and perhaps in Palma later. I don't plan to go to this much trouble for shorter range ammo unless my testing shows it is necessary. I have not been able to test these loads because my range is closed due to Corvid-19 but I am hoping that my velocity SDs and group sizes will improve. I will report back when I get the data.
