"I am a little confused concerning using a funnel to pour my own measured powder through the die. I am interesting in doing this with the shell in the press, can I only do this with the lee press? Also, can you leave the funnel in the die while you index it or do you have to pull it out every time? "
You can do this with the LCT and use the Lee Dipper Cups to charge cases. The photo shows the 45-70 case. I cut the funnel to the appropriate size.
