9mm sizing is harder

I do notice that 9mm is a bit more difficult than straight walled cases, but to the point of adding another step like lubing. is there another benefit to lubing other than effort, because I just don't find it that difficult.

If you leave the lube on, extraction function is more positive and reliable. This was an old Bullseye pistol shooter trick, back in the day when 1911's frame rails were peened, then the slide was beat back and forth over the frame with grinding compound. It was an old trick to drop oil on the top of the five round rapid fire stack. Those old pistols were extremely tight and the loads are the absolute minimum necessary to function the action. (Try to fire five rounds in 10 seconds, one handed, and stay on the 25 yard target with full power loads, tough!) Oil between the case and chamber reduced the friction between case and chamber, and that made extraction reliable, especially with light loads.

Dribbling oil over the cartridge stack is messy, I have done it. Bullseye shooters lube the heck out of their pistols, I learned from them that my elbow is the drip point. :D
 
I'm sitting here smiling about the comment about lubing the rounds. I'm waiting for the inevitable post about hammering the face of the slide due to "increased case head thrust". :D
 
Greg, I do not believe anyone mentioned lubing the round. The only handgun brass I own that I lube lightly is the 9mm. As I stated, I only lube about one piece of brass while sizing and then about the fifth or sixth round as I am reloading the brass. It simply makes resizing and the reloading process smoother. My depriming die is the same die that resizes with handgun brass and primes it.

To me, a round is a complete piece of ammunition. A piece of brass is prior to priming and reloading. Maybe, I misunderstood your post.
