cockercas Posted September 12, 2011 Report Share Posted September 12, 2011 Having problems with the lee collet neck sizing die? Well I know an easy solution. Unscrew the cap of the top of the die and inset a thin washer ontop. Then screw the cap back on. Now screw the die back into the press till its touching the ram. Turn half a turn extra. I checked the internal neck size with a calliper and it was .242 and grips the bullet nicely. Try it. It will solve it Quote Link to comment Share on other sites More sharing options...
Harnser Posted September 12, 2011 Report Share Posted September 12, 2011 I am sure somebody will come along and tell you with 10 pages of arrogant nonsense that what you are doing is all wrong and that you should listen to what he has to say to get it right .

Harnser . Hi, cockercas, Truly hope that I don't fall into Harnser's catagory here. I use these and info on any problem solving is always welcome. Apart from the fact that it gives the mandrel some end float, I've always thought that the end cap was nothing more than a manufacturing closure. By "washer" do you mean that this gives the mandrel more float (ie, the mandrel head goes through the hole in the washer) or is it acting as a shim which locks the mandrel? Although I've polished 0.0005" off the mandrels on the two that I'm using to overcome any spring-back problems (particularly Hornet), all is well. What is the problem that your procedure corrects?

cockercas Posted September 12, 2011 Author Report Share Posted September 12, 2011 Hey phil. When I was sizing the neck the bullets would drop into the case. I don't know what a mandrel is I just unscrewed the cap of the top put a washer on top of the other thing that's in ther and screwed the cap back on.

wymberley Posted September 12, 2011 Report Share Posted September 12, 2011 (edited) Hey phil. When I was sizing the neck the bullets would drop into the case. I don't know what a mandrel is I just unscrewed the cap of the top put a washer on top of the other thing that's in ther and screwed the cap back on. Hi, Probably, the best example of a mandrel is a pop rivet. The spikey bit with the little **** on the end which when pulled through the rivet broaches as the rivet is formed is a mandrel. The die mandrel is the bit with the decapper on the end. To be honest, I don't think that washer (oops, Harnser territory!) will have had any effect. As many have pointed out, Lee equipment is quite cheap and sometimes the finish is not all it might be. If you sometimes use it and the primer pops out and you hang on the lever but nothing seems to happen, nothing has (except, if you look at he other thread on this, if you push hard enough you'll pop the closure cap). That's when the bullets drop in the case. The problem is that it's seized inside due to the sometimes poor (rough) finish. A sharp tap or, definitely, unscrewing the top cap to access the internals will free it off. With experience, you'll get the feel for when this happens. However the situation cures itself with use as the die gets "run in". Cheers, Phil Edit: the **** is another innocuous little word that the PC brigade find offensive. It is slang for "penis", is a small lump and starts with "k". Edited September 12, 2011 by wymberley Quote Link to comment Share on other sites More sharing options...

wymberley Posted September 13, 2011 Report Share Posted September 13, 2011 Hi, Joe, This kept me awake most of the night! Yep, it will work. However, there's a problem. You have four floating objects which are coming together under a load: case, mandrel, former and sleeve. As they come together, they'll take the path of least resistance - a straight line. This is ideal as it means the neck is truly sized along the centreline of the case. Should you "lock" one of the four - in our case the sleeve - this ideal path is not certain. The reverse, but same principal, of this is if you drive along a road with some camber and let go of the steering wheel - the path of least resistance is the kerb, force being required on the steering wheel to maintain a straight line. To be honest, I have no idea what effect this would have on accuracy and may well not be of any great consequence but I figure it's better to treat the defect than the sympton and if necessary smooth out any burrs or irregularities on the two cones so they run smoothly together. Hope that helps, Cheers, Phil Quote Link to comment Share on other sites More sharing options...

Still trying to sort out the group from the 60s - I'm pretty sure I must have been there but I can't remember. :( Quote Link to comment Share on other sites More sharing options...
