I don't get it really, so many people seem to like hand priming.
I like to see that my primers are seated. I can't do that on any of my progressives.
I prefer to clean cases after resizing, old habits die hard, which affords me an opportunity to prime the case off the press and give the cases another inspection.
I like to reload. But it is a restful hobby so I do not wish to induce lots of worry.
I resize and prep cases shortly after shooting them. Then store them for a future reloading session. Small batches go quick. Hand gun cases are resized and expanded on a Hornady L-N-L. I just install the dies I need for the task at hand. A nice advantage of the L-N-L bushing system over the tool head system on the other progressive presses.
By resizing and priming at a different time as reloading, I can concentrate on dropping powder and seat the bullets.
I still load more ammunition faster and in greater quantity than I can shoot.
It works for me. Lessons my work load. Reduces the risks of squibs
for me.
It does not work for everyone.
In recent time, large batches, 500 or more cases, of priming with a hand primer is hard on my hands so I now do large batches of priming with an RCBS APS bench priming tool.
Small runs, 100-200 or so cases, I still hand prime as it is quicker than setting up the bench tool. Then bench priming tool is stored away except when I plan to prime a large batch of cases. If the bench priming tool was permanently mounted to the bench, I'd use it for small batches as well at times.
Final note, I can fill the primer tray and prime 100 cases with a hand primer faster than filling a priming tube.
That's why I prime off the press.
