Does this warning from Lee apply to both the new and old style priming tools?RCBS Ram Prime works for me on a single stage press. Slow & to easy to drop a primer.
But no chance of detonation of the primer feed/tray.

Federal primers may contain some Nitroglycerin*. See their SDS. Other brands, no nitro.
Primer kabooms are from operator errors, not a primer brand issue. Imo.
