Yup. As said before, these things can be picky! I had all sorts of problems and started trying out the Remy bulk and my problems went away. Went back to some of the other stuff and the problems came back.

I believe a lot of it depends on what and how the firearm was broken in as well. Mine was bought used so I couldn't tell you about how it was broken in.

What works for someones may not work for others as well.

To answer your question as accurately as possible - I was getting FTEs, DFs, and FTFs.
