jcwit, I am using a factory crimp die.. i am doing what I would say is a light crimp...
There are those who feel the post-sizing performed by the Lee Factory Crimp die will cause the bullet to be undersized thus adding to the possibility of leading the barrel. I have not had that problem but I don't doubt those who report having that problem.jcwit, I am using a factory crimp die.. i am doing what I would say is a light crimp...

Try crimping with your seating die and eliminate the FCD and see if that helps the leading situation.

I do not recommend the use of FCD for lead bullets in semi-auto calibers. If a reloader is experiencing leading with FCD, a simple test would be to load some test rounds without it. If leading decreases or goes away, then load the lead rounds without the FCD.cowtownup said:I am using a factory crimp diejcwit said:are you using a Factory Crimp Die?
I did the same with frustration until I wrapped some copper strands (Chore boy) around an old copper bore brush to remove the leading. Now, one dip in Hoppes #9 and a few strokes will remove the leading and I have a clean barrel.I was unable to remove those deposits with brush and patches... I actually had to let the barrel sit for a while in Hoppes ...
No, unless you want to. As others already suggested, I do the following to minimize/reduce leading when shooting lead bullets:Is this just a part of shooting lead bullets or do I need to keep trying to work up a load that does not lead the barrel as bad?
I think velocity/leading is relative to the bullet-to-barrel fit/lead alloy hardness/powder burn rate/powder charge.Does velocity of lead bullet affect how much lead it leaves in the barrel?
