I used a Magnetospeed Sporter before getting a Garmin. The only gripe I have with it is no matter how tight you get it ,it will slide on heavier recoiling rifles. I still use it time from time.
I still use bushing dies on 3 cartridges 338 LM , 7-08 , and 25 Creed. All 3 are FL sizing dies and set neck tension with bushing , no expanding. Bushing numbers down and lightly loose in the die as you described , with no doughnuts.
I used to size the 30-378 Wby with a Redding neck bushing die...
I just used my original disc and it installed without a hitch. After installing I installed the latest update I had on hand. The only thing I don’t care for on my laptop is it does fill the screen like my desktop did.
