    Yep. I drop them as if I were actually loading ammo. Seems the best way to tell what's dropping under normal use

     

    This is true.  My theory is that activating the powder measure by hand is typically a little more gentle compared to operating while running (which I find is faster and the action/vibration while loading may allow a little more powder to settle into the bar).  Also, when activating by hand, you really need to set aside (recycle) the first few throws as they tend to be a little bit heavier in my experience (if powder has had time to settle more).

    Yeah, its quicker and easier the other way though. I will probably ballpark it that way, then fine tune with using the rod.

     

    I have done that for the same reason, it is easier/faster.  But, see my comments above.

    what RDA is saying about the ogive affecting OAL is correct but I'd amend it slightly to say the ogive MAY be contacting the seating stem. many type of bullets will contact the tip of my fairly flat lee seating stem. 

     

    best bet if you are interested is pull the seating stem and see for a given bullet does it contact the ogive or the tip?

     

    Agreed, depends on the seating stem and bullet profile, I was avoiding being too comprehensive on the topic based on the discussion to this point and speaking to the most common scenario.

    Well, since the OAL is the measurement taken between the case head and the bullet's tip, please tell me where the length of the cartridge case has anything to do with that.

     

    Brass from different makers will result in different bullet seating depths due to variance in case wall thickness.  Also, there is variance in the case rim area between makers of brass which can contribute to COAL variance.

    The ogive of the bullet I use has no relevance to anything because it doesn't change. My concern is the length of the bullet from case head to bullet tip. I have already found that my seating depth will not put the bullet into the rifling, so my only real concern is OAL from a pressure standpoint.

     

     

    Because the seating stem contacts the ogive.  If there is variance in the bullet profile, the seating depth can vary (even though all the bullets may be identical in length).

    Here is just one of many threads on this topic:

    Type, or length of brass does not effect OAL.

     

    Sure it can.

    I'm using PD 115's and they tended to stay under a thousandth when measured.

     

    You mean the length of the bullet varies under a thousandth in length when you measure its overall length? That's great, but how well do they measure based on the ogive? Bullet profile consistency is more relevant than consistent bullet length when it comes to COAL consistency (if your concern is simply reducing COAL variance).

     

    Ultimately, this fine of variance in pistol cartridges is irrelevant.

    I checked this morning and I was seeing .005.

    I'm going to try a Whidden tool head that locks down (Uniquetek) on my 550, with a Redding pro seater. I'm expecting less than .002.

     

    What type of brass? Mixed or same headstamp? What type of bullets? How consistent are they? Those things will contribute to more of your variance than your 550 in my opinion.

    Case closed, I emailed alliant to ask if and when they would return my little reloading buddy? They gave me bad news, they did some testing and said it was actually their moth and they were glad to have him back. I was heart broken knowing I would never see my little reloading buddy again :( then today in the mail ( actually ups) a pound of BE-86 showed up :) it can't replace my little buddy but it may keep my mind off him.

    So I am an alliant fan boy!!!


    Nice, and thanks for the follow-up.

    Just guessing. I mix it until it works. Too little and it doesn't help much. Too much and it funks up the CF plate etc.

     

    All that matters in the end is you can distribute a proper amount of the lanolin reasonably well onto the cases and the carrier (alcohol) evaporates (whether a 20% solution or a 5% solution).  

     

    :)

    Somebody once posted on here they kept thinning a bottle of Dillon lube with alcohol for years and it still worked great so I mix mine about 20% lanolin I think.

     

    20% or 20:1 (alcohol:lanolin)?

    20% would be some thick case lube.  I think I initially tried 12:1 the first time and 15:1 the second mix.

    I am saying there is some degree of slop built into the use of a roller camming pin.

    Start by adjusting per Dillon 650XL manual and having several cases in the feeder.  Pull handle to bring a case down to shellplate level.  As you raise the handle and the shell plate rotates....SLOW DOWN and watch when the case enters the slot in the shellplate.  Too early and the case will "ride" the outside of the shellplate. 

    Rotate the camming pin a full turn and pull the handle down, then up.  Again slow down to watch the case.  Rinse and repeat until you have the case entering the slot without it riding on the outside of the shellplate.  (don't forget to remove the first case once it has rotated to Station 2)

    The difference between stock Dillon and roller cam is the adjustments can not be precise with the roller cam because you only have half turn increments.  Dillon's can be micro adjustments.  Fortunately you do not need micro adjustments.  You can keep the roller set to the beginning of perfect entry or the end of perfect entry....and from my memory, this was two and a half full turn options.

    btw, I now double nut lock my roller cam.

    I see we are talking about two different things.  I was thinking about the cam follower for the shell plate (picture above)? You appear to be talking about the cam follower for the case shuttle (station #1).  I was thinking this thread was in reference to the one pictured above but rereading the original post, I am not certain while one was being asked about originally..

    Forgive me.  I am a mechanical engineer by trade and my critical dimensioning is measured to .0000

    A complete spin of the cam pin WITH ROLLER will result in two positions where the roller is correctly aligned.  0/180º or 90°/270° depending on how you look at it....otherwise the roller is not rolling...but now dragging with no roller spin...not the intended purpose obviously.  I have found that there is a range of 2.5 complete turns that will get the case into Station 1 at the correct time to avoid snapping/jolting.  So you have 5 alignments (2.5 turns with 2 positions each full turn) that work properly.  5 is not a precise measurement....but it is CRITICAL that you get one of the five positions.

    How much play is in this roller cam?

    23 hours ago, amada8 said:

    The adjustment is not critical, but is important as the position of the cam ensures the new empty case's arrival at station one to be in sync..... or not.

    This seems contradictory to me, you say the adjustment isn't critical but the position is important for the case's arrival at station one to be in sync?

    Just called PV talked to the usual gal and she said that they are aware of the problem and the new site is not finished.  She said even though it might say something is available it still might not be.  I would probably call in your order for awhile just to make sure.

    Definitely a very bad deployment of a new site.

    Our order is COD so No harm no foul.

    Powder valley needs to get their stuff together.

    Because that means they have been hacked.

    Because once my buddy signed on it populated all his info, and that could have only came from PV.

    You sure that wasn't his browser or an app he has installed that pre-populated the fields? I have serious doubts the real Powder Valley Inc was hacked.

    When I click on the op link this is what I see?

    I know, I see it that way as well now, but it wasn't that way when I first posted (I provided a screen shot of the way it was).  They obviously updated the web page to provide that information.  I have both the old webpage and the new webpage open in my browser and can see the difference.

    I had an ammo load stepped 9mm case somehow get by and into the machine, the powder check found it.
     
    I wired into this particular PC die as it is an input for the PLC that normally runs this machine but it is otherwise as it came from Dillon.
     
     

    Confirms my results as well.  I set up the Dillon powder check where it operates in a fairly tight range and can detect a few tenths of a grain difference (over or under) as well as case volume issues (dirt, debris, spider web, stepped brass).  Although I visually check, I consider the Dillon powder check a great tool for producing consistent quality ammo and can detect things I can't visually detect.

    Quick side note -- I never understood what people were talking about with the "primer ski jump" on the 650. Now I get it. I had a few primers that didn't get decapped (took me a few tries to get my pin adjusted correctly). That design is just pure silliness! Kicking out live primers just because there was nowhere for them to go? Why can't they go around the circle again? 

    I don't think they want the live primer rotating back under the stack of live primers.
