Is there a down side to Federal primers?

[DCC]

Yup - Due to light springs I use Federal in some of my revolvers. My Webley's don't care what I use...they whack 'em so hard they're not fussy.
Downside is cost.
Never, they say never say never, had any problems using Lee kit.
Did some crude testing a few year ago crushing various primers in a vice and nothing went bang.
Maybe someone here can in the trade can confirm that there is a ball bearing drop test carried out by manufacturers and the military to ensure that primers are not overly sensitive.

The downsides for me are the packaging is huge, they are typically more expensive and they can be hard to find. Even with those downsides I still prefer to use them in most revolver loads.

RCBS has a large square primer tray/flipper that fits the Federal perfect. They are a PITA with the round style trays
