snow white Posted February 8, 2015 Report Share Posted February 8, 2015 Why is my Lee challenger press putting heads in different depth any body help please. Thanks for looking Link to comment Share on other sites More sharing options...
dannywayoflife Posted February 8, 2015 Report Share Posted February 8, 2015 Are you pressing with differing pressure? Are you sorting your bullets to the same ogive length? Could be many reasons mate. Link to comment Share on other sites More sharing options...
MJR Posted February 8, 2015 Report Share Posted February 8, 2015 What kind of bullet? VLD bullets need a different seater. Link to comment Share on other sites More sharing options...
snow white Posted February 8, 2015 Author Report Share Posted February 8, 2015 Vmax 55 the ogive should be 1.813 the press is verying bettwen 1.800/1.820 overall length is 2.210.can not work out what is the matter Link to comment Share on other sites More sharing options...
MrCetrizine Posted February 8, 2015 Report Share Posted February 8, 2015 What seating die are you using and have you cleaned it recently? Link to comment Share on other sites More sharing options...
snow white Posted February 8, 2015 Author Report Share Posted February 8, 2015 I am using rsbc dies cleaned them when I had them couple weeks ago can not understand why it happening it is a right pain to say the least Link to comment Share on other sites More sharing options...
Murph Posted February 8, 2015 Report Share Posted February 8, 2015 Are you pressing with differing pressure? Are you sorting your bullets to the same ogive length? Could be many reasons mate. Sound to be spot on. When I used to do it and measured to the tip there was always a variation. If you measure to the ogive they should be bang on. I use a challenger with a forster micrometer die and it sets the bullets to within a thou no problem. You will get varying lengths between tip to ogive on most bullets.

snow white Posted February 8, 2015 Author Report Share Posted February 8, 2015 I am measuring to the ogive just can't see what is going wrong? Link to comment Share on other sites More sharing options...
MrCetrizine Posted February 8, 2015 Report Share Posted February 8, 2015 Is your die definitely touching the shell holder with no play or movement between them? Link to comment Share on other sites More sharing options...
onehole Posted February 8, 2015 Report Share Posted February 8, 2015 Sounds like a classic neck tension variation to me probably with being too tight and deformation of bullet head at seating die contact point.Given the forces of a press you may not feel whats actually going on,,,,,,mmm,,,,O Link to comment Share on other sites More sharing options...
jon Posted February 9, 2015 Report Share Posted February 9, 2015 Also sounds like what Laurie describes in ... 7Mm seater stems .. down this page?? Link to comment Share on other sites More sharing options...
snow white Posted February 9, 2015 Author Report Share Posted February 9, 2015 Hi the die is not touching shell holder I cannot see how it can.I am using a Lee shell holder is there a difference between shell holders.there must be a gap of 4mm between holder and die.thanks for your help Link to comment Share on other sites More sharing options...
gbal Posted February 9, 2015 Report Share Posted February 9, 2015 Hmmm....what are you measuring bullet seating depth with? Have you had such base to ogive variations (20 thou) in seating depth in the past ? Do you get very consistent depths (base -ogive) when you measure the same loaded round several times? (as a last resort,does it actually show on target?) Â gbal Link to comment Share on other sites More sharing options...
Toby Posted February 9, 2015 Report Share Posted February 9, 2015 Silly question but is your brass all trimmed to same length? This and the bullet variance may have something to do with it. Link to comment Share on other sites More sharing options...
snow white Posted February 9, 2015 Author Report Share Posted February 9, 2015 All brass are the same length. Everything is the same from the first to the last.why o why does nothing go right for me ? Link to comment Share on other sites More sharing options...
onehole Posted February 9, 2015 Report Share Posted February 9, 2015 Check your seater stem is not split,,will be a micro split best looked at with a 5 or 10x lens?? Also check your press is not set up to press home the bullet at the bottom of its stroke as there can be play in the "overcam" position.,,,,O Link to comment Share on other sites More sharing options...
snow white Posted February 9, 2015 Author Report Share Posted February 9, 2015 Hi onehole checked for split all OK was wondering if the shell holder is to blame it is a lee one should it be a rcbs shell holder tried everything you lads have told me to try made a round up with out powder and primer setted it to required depth pulled head out tried it again different measurement.tried it halve dozen times all different really fed up have less trouble loading 20 bore Link to comment Share on other sites More sharing options...
gbal Posted February 9, 2015 Report Share Posted February 9, 2015 ?"setted it to required depth"...? how? But it did not repeat seating depth...As before,how are you measuring seating depth-what tools? Cartridge OAL is largely irrelevant,as bullets vary in length,;they vary much less base to ogive -either the die is seating variably,or there is a measurement error....or both...has this happened before with this kit and proceedure? gbal Link to comment Share on other sites More sharing options...
MrCetrizine Posted February 9, 2015 Report Share Posted February 9, 2015 Hi the die is not touching shell holder I cannot see how it can.I am using a Lee shell holder is there a difference between shell holders.there must be a gap of 4mm between holder and die.thanks for your help On all my Lee dies, they touch the shell holder when the ram is all the way up.

snow white Posted February 9, 2015 Author Report Share Posted February 9, 2015 I am using dial callipers cost fortune Lee lock load ogive tool not measuring oal length just to the ogive.measured some heads and the very as much as five thou horndy 55 v max.tried all the things that as been suggested.

gbal Posted February 9, 2015 Report Share Posted February 9, 2015 Snowwhite,thanks-a really good micrometer is near essential if you are concerned with a few thousandths-and a good depth guage/comparator like the Davidson or Sinclair attached to the blade of your callipers,with the right bullet insert.And very good ,consistent 'feel' in using it. So have you had these problems before,and have you actually shot any of the 'variable' depth bullets-some rigs are quite tolerant of variations,and short term,well good enough....and some are not! Â Are your primers all seated flush,and not protruding variably from the case-you might get increased bolt closure pressure if they are. Also,a stray kernel of powder can add 10-15 thou to 'measured seating depth' so keep scrupulously clean. g Link to comment Share on other sites More sharing options...
onehole Posted February 9, 2015 Report Share Posted February 9, 2015 I think by now I would be looking to buddy up with someone for a practical hands on look of all your kit and procedures.......would have been glad to help but your probably a million miles away,,,,,hope you sort it anyways,,,regds ......O Link to comment Share on other sites More sharing options...
Offroad Gary Posted February 10, 2015 Report Share Posted February 10, 2015 Ive just changed from a lee press to a lyman orange crusher because i was unable to bump shoulders accurately enough in my "precision" rifle. Problem solved in an instant. The lee press was the last part left from my starter kit bought years ago. Link to comment Share on other sites More sharing options...
snow white Posted February 10, 2015 Author Report Share Posted February 10, 2015 Hi I am using a comparator everything is spot less. I am going to strip press down today the reason I am doing this is I have a new rifle coming and want to set up new rounds for it keeping my other 223 for day scope.what started as something simple as turned in to a nightmare I just checked a couple of rounds and the was different using ogive as I was measuring OAL before how many have I made like this in the past.I am the sort that if you are going to do something do it right.which I had not brought the ruddy ogive now with the headache it as given me but THANK YOU ALL FOR BEING SO HELPFUL. Will let you now if something wrong with press. Link to comment Share on other sites More sharing options...
drum Posted February 10, 2015 Report Share Posted February 10, 2015 I had this problem myself using a lee classic press,lee shell holder and dies,thought that poor quality equipment was to blame until i realised that poorly seated primers were the issue.Perhaps seat a bullet without powder or primers and see if you still have the variation.Incidently i never had any issues on target because of this.
