Generally speaking yes, it would be easier to overcharge a 9mm than .223 unless someone TOTALLY spaced it and say left pistol powder in a measure, and adjusted it for a .223 charge, and loaded away.It's a lot easier to overcharge a 9mm to dangerous levels than it is a 223
I have heard of this a couple times in my shooting 'life' where someone loaded rifle rounds with Bullseye or similarly 'fast' powders - with expected results - and recently read of it happening on another forum.
Even loading my .30-30 rounds with 9-10 grains of Unique a double charge would not overflow and I am very careful when loading them and have a 'procedure' I use which nearly eliminates the possibility of a double charge.
