Maybe to leave some slack for the .010" they give you to play with. Seems excessive to me. The Lyman has .095 deck thickness, but there is also a slot in the middle of the deck for easy entry?

Seems to my imagination, since the ram end point of movement does not coincide with the handle end of movement you might have to work the handle while you adjust the die. The other way would be to know the amount the ram dropped after TDC and add that to the shim thickness. One method would require a slight bit of "feel." the other would require a consistent fall of the ram after cam over.

The slot has to do with primers. The no slot has to do with primers. It is a way to protect reloaders from them self's. I have shell holders that do not have a slot, no slot prevents the reloader from removing a case from the shell holder if the case is for an auto loader. We do not want cases with high primers. F.

I said something although accurate I believe it could be a bit misleading in the context of this thread .

Sorry group. I apologize for mistakingly using CW308's handle in reference to a problem that Metal God described. My excuse is its a long thread and I'm easily confused. But then any who read my posts understand that.
A thought occurred to me of a difference between cam over and non cam over resizing. With a non cam over press the eventual final amount of pressure used is determined by the brass. I'm saying one case may require more pressure to reach the stop than another. In a cam over press the cam over pressure would be more consistent. I have never had a case keep me from camming over. Hopefully that means the camming force is more consistent than the brass's resistance. My way: annealing every time provides a very consistent resistance to resizing. In my mind consistent resistance and consistent force by over camming makes consistent cases. Consistent ammo is a precursor to long range accuracy. I know there hasn't been a correlation between accuracy and annealing, but when I resize and seat bullets I can feel the consistency. It has lowered my SDs for my ammo. That is objective benefits to annealing. I know it is generally accepted that annealing prolongs brass life. Is there objective proof of this? Just an old guy with to much time for thinking. |

For reloaders that are afraid of loosing their place' and they are sizing 30/06 and 308 W cases it is possible to set their die up for the 30/06 case and then switch to the #3 Extended shell holder when sizing the 308W cases. there is a difference between the standard #3 shell holder and the #3 extended shell holder. the difference? The reloader without the extended shell holder has to adjust the die to the ram when going back and forth from the extended shell holder and the standard shell holder. I have always thought threads in the press and on the die were there for making adjustments. F. Guffey |

Alot a talk on cam over , There my not be a right or wrong . I think it's a matter of feel , what I feel is a dead stop others may add alittle more muscle. I would think adding muscle would stress the press . I never got into heating brass., some of my friends do with good success in sizing and brass life . I don't own a chronograph to check velocity , l guess I'm still old school and see what happens down range . My reloading is on a single stage press , rifle reloading l reload 30 rounds each week , so l can take the time in trimming every time , lube and size then back in the wet tumbler to remove lube , all my cases are uniformed ( pockets ) flash holes are deburred and make sure flash holes are the same size . I can do this because I have the time only doing 30 , some say it's a waist of time but I have it . I take the same time in setting up the press . My sizing is smooth with very little resistance and I can size all my cases to .000 to .002 what ever setting I chose . Using a dead stop or cam over or what ever you want to call it , I still say if stress has to be used to get there your doing something wrong , cases aren't clean , not enough lube or maybe even your in to much of a rush , if so , cut down on your quantity and concentrate on quality. F.Guffy did I cover any unanswered questions. Chris |

"with end movement' with a cam over press the end movement of the ram is called 'bump' on a cam over press. SO When adjusting the cam over press the ram is moved over top dead canter meaning when the ram passes the bump stage the ram moves away from the die. Yes, the ram bumps twice, once on the way up and once on the way down if the reloader can get a grip on the concept' the ram must move up before it can be lowered. And now the impossible part to understand. the die must be adjusted to contact the shell holder between the two bumps (rock back and forth), if a reloader was able to measure the amount of cam over they 'should be able to determine the amount of sizing in thousandths. If the die is adjusted on the top of the bump the die is lowered when the die contacts the shell holder. If the reloader understands the concept of '0' he can measure the amount of cam over with a feeler gage placed between the top of the shell holder and bottom of the die. And no it is not necessary to start over everyday. It is not necessary to measure the amount of cam over everyday, once is enough for a life time. F. Guffey |

I said the Rock Chucker is not a cam over press. I said I have 3 Rock Chuckers, I said all of my Rock Chuckers lock up and go into a bind when the ram hits the top of its travel. I said the bind is caused by the linkage' all of my Rock Chucker rams kick forward at the top and back at the bottom and I say I am the only reloaders that knows and understands that because I can not get another reloader to back away from the keyboard, get out of their chair and then crawl under the bench.. You can disagree with those that do not agree, if they start insulting you, you are better off without them. Something like the song about Caldonia. I have insisted the case is the aligner, without the case in the shell holder for alignment the ram does not align with the shell holder. It is not necessary for a reloader to get out of his chair to watch the ram kick back. And as I have said before the ram is a solid bar, if the top is kicked forward the bottom has no choice but to kick back. F. Guffey |

I have brought this up before.
Please describe cam over. I call it linkage going over center so the ram goes up exactly the same distance every stroke. Lever goes down. Ram goes up. Lever goes past center of the linkage. Ram goes down just a teeny bit. Lever pushes firm, then gets easy that last little bit of the stroke. Is this a cam over press? If not I have never seen one. I have a rock chucker. David |

When thinking of cam over , I'm not only thinking of my press but any press if it designed or not for cam over , if it bottoms out at the top or kicks back . What I feel and that's just me . I can size my cases to the size I want and can get there without stress , is the way I like the press to work . You can twist it anyway you want and can talk until your blue in the face , that I don't know what I'm talking about or will not answer your questions . I'm giving information and only my opion what works for me . This type of BS doesn't help or answer the post . People have to try and see what works and what doesn't , we suggest what works for us . Not who's right or wrong . Hope I Helped in some way Chris PS I like my RockChucker . I don't have to mess with bind or rock back and forth , why would you want a press like that anyway . Just up and down and centered . Last edited by cw308; January 30, 2019 at 11:15 AM. |

I do not know about other reloaders with Piggy Back attachments but my Piggy back attachments have pins for alignment when the ram hits the bottom, the pins lock the shell plate in place' and then there is the one way clutch, my piggy back attachments have one way clutches, if the ram turns in the opposite directions the one way clutch is rendered scrap. There is nothing that grabs hold and locks down like a set of tongs, Ridgid pipe wrenches and a one way clutch. And then there is RCBS, they have a parts catalog for Piggy Back attachments and presses. F. Guffey |

And then I made a tool for annealing based on 'the rules'. it was cheap, easy to make the only thing I could not do was make it fool proof' because fools do not read. It still works as designed but I have avoided discussing annealing because of the reloaders desperate attempt to be the 'go to guy' it has only gotten worst. F. Guffey |

.010" is .001" more than the difference in length between a minimum length/full length sized case and a 30/06 no-go head space gage or .005" longer than a go-gage. I suggest you guys avoid traveling down rough roads with your presses. I can imagine parts flying off of the presses because of the loose fitting parts. F. Guffey |
