I have found another interesting behavior- this one probably a minor bug...not a show stopper ... follow along...

Create a new firearm, give it a name like "S&W M&P Sc". Go ahead and fill in some of the data fields such as Manuf-Model-Style so we have some unique data, then create a couple new empty loads and just change their name title to 155 gr and 165 gr, change their bullet weight appropriately but don't enter any more data.

When done right click the "S&W M&P" firearm entry and create a duplicate copy. Click on it and rename it to XD-Svc. Change the manuf. to 'Springfield' the model to XD and Style to "Service".

DO NOT move the focus (current cursor position) off of the newly created XD record. Now right-click its name in the tree view and create a duplicate copy of the XD entry.

Mine creates a new firearm record called "XD-Svc Copy"

NOW change focus to that new copy by clicking on it in the tree view with your mouse cursor...

Mine auto-magically changes its name to "S&W M&P Sc Copy Copy" and all the data in it accordingly to the original S&W stuff.

However If I move off the XD-Svc record and back to it before creating a copy of it, all goes well and I get a copy of the XD record as expected.
