J1mc Posted January 6, 2020 Share Posted January 6, 2020 I am having issues with the powder funnel popping when running a 1050 on an ammobot. I am lubing cases and that helps, but the popping is sometimes very violent. I have reduced flare on case mouth to as minimal as possible and seemes to make no difference.

4n2t0 Posted January 7, 2020 Share Posted January 7, 2020 (edited) I think chevrofreak wanted to know which headstamps you're trying to load? Edited January 7, 2020 by 4n2t0 Corrected a mistake... Link to comment Share on other sites More sharing options...
chevrofreak Posted January 7, 2020 Share Posted January 7, 2020 CBC isn't stepped, it just has a ton of spring back and grabs onto the powder funnel like crazy. Link to comment Share on other sites More sharing options...
4n2t0 Posted January 7, 2020 Share Posted January 7, 2020 (edited) Several things can cause the powder funnel to stick. 1) New brass is especially sticky. 2) Not all brass is created equally: 3) Brass has galled on the powder funnel (look for a light brass ring or brass streaks). 4) You're pushing the powder funnel too far into the case (too much flare). 5) Your powder funnel is too thick. I just polished my powder funnel but you can also modify it. 6) As you have already learned, case lube make the press run smoother. 7) A million other reasons that I've forgotten.

My eyes aren't good enough to tell what the modification to the powder funnel is. Could you describe it? Thanks! Link to comment Share on other sites More sharing options...

I'm also having trouble seeing how you modified the expander on the right... Could you post a close up image? Thanks! Is that a DAA powder funnel or a Dillon?

4n2t0 Posted January 9, 2020 Share Posted January 9, 2020 (edited) Sorry for the late reply, please allow me to clarify... I only needed to polish my MBF powder funnel with metal polish to get rid of the problem. The picture is a stock photo of a Dillon powder funnel which has been modified by Starline. It's hard to see but the radius of the funnel was modified to smooth entry and exit. When performed on a MBF powder funnel one must be mindful of the "step" in the funnel.

Question: Isn't the step on the MBF powder funnel one of the reasons it does such a good job on flaring as opposed to the stock Dillon? I know that I like it better than the Dillon anyway...

J1mc Posted February 5, 2020 Author Share Posted February 5, 2020 Update: Looks like after about 300k rounds and a couple of polishings my DAA exspander was worn out. Ordered a new one and it is working as it did originally. The new one is dimensionally different. The funnel mod pic is what clued me in to check and see what a new DAA funnel looked like compared to mine. Thanks for the help. Link to comment Share on other sites More sharing options...
