Monkey see Monkey do.
Natureboy, keep reading and learn who knows what they are talking about and ignore the rest.
There are a lot of folks simply repeating what they hear and what they see, don't mimic them unless the practice is obviously correct. When something doesn't sound right, look to find sound verifiable expert opinions on the subject. (This is the right place.)
Then get confirmation, from another expert. Learn to differentiate: experts from the actual applied field, experts of theory (those who read more than they do), and idiots who are really lucky most of the time.
I won't touch the "ignition" question that this thread has deviated into (covered that in a thread long ago), but will say, with regard to the OP, that my ball starter has a shallow hole in the handle that goes atop the loading rod for a one single final tamp of the load each and every time. I learned this technique from a few expert shooter members here.
Accuracy demands consistent compression of the load. (all powders, all theories, ever)
Keep reading, keep learning, keep away from those who are unsafe (and try to educate them if you can, but don't expect much). Public ranges are about the scariest places I've ever been.
This sport is as safe as fishing, at least!
