Clever.
Just a edit:
Lee warns against using Federal Primers in their hand held primer tool as they have found they chain ignite and go kaboom!
Lee did a lot of testing years ago after some handloaders had primers detonate in the original round tray Auto Primes. As a result of the testing, Lee recommended using only CCI and Winchester primers.
This isn't just Internet doctrine of dubious worth. In fact, the evaluation was done long before the Internet. It was written up in at least one magazine and it may be included in the Lee load manual. If not, I'm sure Lee could steer you toward a copy of the article and testing.
This is the reason the original "dangerous" version (the one that worked well) was discontinued and replaced by the safer square tray model.
