As I posted last week I got a new to me RL1050. Thought I would post my thoughts so far. Got the press already set up for 38 Super about 10 days ago. Called Dillon the same day and ordered the conversion kit for 40 S&W since that is what I am shooting in competition and the majority of what i load. I have been doing about 1000 per week for the last few months on my LnL with great results. Exactly 7 days after i got the press the conversion kit arrived. I was somewhat apprehensive with the reports of the difficulty changing things out. While it was not a 5 minute job, I got it up and running in about 2 hours. I think I could do it in about 30 minutes now. Loaded up 4 of the included primer tubes, dumped a butt load of brass in the case feeder and started pulling the handle. One word... WOW! This thing is amazing! I now understand why Dillion makes the auto primer filler thingy. The primer alarm started a buzzing and I was thinking, what the hell is wrong with that thing. Nothing. It was empty in about 3 minutes. Loaded about 1000 rounds this weekend and shot in a match. Total time loading was less than 2 hours. All rounds are exactly the same OAL, the powder charges with VV N320 are EXACTLY the same on my scale. Very impressive. I should have bought one of these things years ago.
