Mavrick379 Posted March 2, 2014 Share Posted March 2, 2014 I'm having a small problem with powder (H110) trickling out of the powder mearsure on my550B. I have narrowed it down to the powder is sticking in the steel tube that is pressed into the aluminum powder measure body. The steel tube has small ridges on the inside and is not smooth by any means causing flakes of the fine H110 powder to hang up in there then fall out onto the shellplate from vibration. Its not a huge deal but the flakes get into my primer cup causing a dent in the primer unless I blow it off every 20 or so rounds. Is this something that is just accepted and is "normal" ? Why is the inside of the steel tube not smooth? There must be a reason. Link to comment Share on other sites More sharing options...
Steve RA Posted March 2, 2014 Share Posted March 2, 2014 Polish it, makes quite a difference. Link to comment Share on other sites More sharing options...
Mavrick379 Posted March 3, 2014 Author Share Posted March 3, 2014 I would if I knew how. I did polish all the aluminum to a nice bright shine but since that tube is steel and its on the inside how do I smoothen it out? Link to comment Share on other sites More sharing options...
leewongfei Posted March 3, 2014 Share Posted March 3, 2014 Dont polish anything, I actually completely disagree with Steve on this. Please follow the link for an official response from Dillon about this same exact issue. I did this, and i have never had any powder spillage happen since. You may need to copy and paste the link, i dont seem to have the ability to paste a link. "It sounds like the powder flakes are sliding between the powder bar and spacer. Put a piece of tape on top of the spacer bar to shim it down a few thousandths." http://www.dillonprecision.com/Leaking_Powder_Measure-98-11-1069.htm Link to comment Share on other sites More sharing options...
RDA Posted March 3, 2014 Share Posted March 3, 2014 Dont polish anything, I actually completely disagree with Steve on this. You and Steve (and the OP) are talking about two different things I believe. Link to comment Share on other sites More sharing options...
Mavrick379 Posted March 3, 2014 Author Share Posted March 3, 2014 Already took care of that part, dillon actually sent me some new thicker bars and it helped alot. A few flakes of powder trickler out of the powerder funnel after I lower the ram, I can see it happen, this happens because the vibration from operating the press causes a few flakes that were hung up in there to fall. If you look at the inside of your powder funnel and the steel tube above the powder funnel they are both very rough on the inside, this is where the powder is hanging up then falling from vibration. My question is how do I smooth up the inside of these two parts, polishing at this point won't work because its way to rough and its very difficult to get in there. Take yours apart and look at it, I bet its the same, I don't know why they manufacture them like this? Link to comment Share on other sites More sharing options...
HighCountryStalker Posted March 5, 2014 Share Posted March 5, 2014 Take a small drill bit, one that is absolutely smaller diameter than the opening of the tube. Wrap a little fine grade steel wool around the drill bit and using an electric drill slide it in and out of the tube. It will polish up beautifully. Just be careful that the steel wool covers the bit so only the steel wool touches the material. Also flush it afterwards so no grit remains.

Prebaned Posted March 5, 2014 Share Posted March 5, 2014 All my powder funnels insides are horribly full of machine marks. I polish everything I could on my 650 but the inside of these powder funnels I cannot figure out how to get these tool marks out either. I'll try the Steel wool tip.

Mavrick379 Posted March 6, 2014 Author Share Posted March 6, 2014 I'm going to give that a try too, thanks for the suggestion. Link to comment Share on other sites More sharing options...
Mavrick379 Posted March 7, 2014 Author Share Posted March 7, 2014 No go on the steel wool, it did shine it up but the ridges are still there. Any other suggestions? Link to comment Share on other sites More sharing options...
jmorris Posted March 7, 2014 Share Posted March 7, 2014 (edited) A 21/64 reamer will give you a nice finish, a lot faster than polishing too. Edited March 7, 2014 by jmorris Link to comment Share on other sites More sharing options...
HighCountryStalker Posted March 8, 2014 Share Posted March 8, 2014 Yea, if the machining ridges are built up that much the reamer is likely your best bet first then clean up with the steel wool. Link to comment Share on other sites More sharing options...
omnis Posted March 31, 2014 Share Posted March 31, 2014 I have been having the same issue using H-110 as I am reloading for 300 Blackout. Over the weekend, I swapped out the small powder measure for the large powder measure on my 550. Problem went away! I had read on several forum sites including other posts here about this idea. I had no problems getting down to the 18+ gr load for my recipe. Link to comment Share on other sites More sharing options...
