CIS is a collection of "workarounds".

I prefer Mfi or Motronic, i loathe CIS.

There's a reasonably good book on FI, Bosch Fuel injection by Charles o Probst
Does a great job at explaining things and isolating problems

Azzy, why the interest in CIS? Do you enjoy pain?

Is your 72 T MFI or carbs?

[GH85Carrera]

One of the reasons I looked for a Carrera and not an SC was CIS.

Good morning folks

the moly was annoying. i didn't notice that they were moly bullets until i opened them. really messy.

there was another major hiccup, but i'll just shoot all those primed cases and re-prime them. nothing dangerous.

Most dies have a case crimp feature. Its not enough of a crimp for an autoloader but a roll crimp for a bolt action. Sounds to me like the bullet is set to depth beffore the crimp is coming in contact with the case. You can probably back out the seating rod and check the case to die contact. If you can pull the bullets out with your fingers I would do so and either attempt to re-seat them or pop the primers but do not leave the bullets in and shoot them.

What kind of crimping die do you use?
What kind of crimp did you set (did you measure the good ones vs the bad ones)

single, lee hand press. crimp on the seating die.

moly reduces pressures and velocities, so generally you would need more powder to get the same velocities as non moly.

and it will make your non moly bullets fire in odd ways if yer barrel is molied up.

yeah, i read about the moly. due to the length of the barrel on my rifle (26 inches) i doubt there will be much of a velocity loss. i read that the loss was about 80ft/sec, anyway. i wasn't loading these for competition, so i doubt the moly will be an issue. my plan was to shoot what i have, clean the barrel, and shoot the non moly. i'll go buy some different bullets this afternoon and try again. that moly crap was painfully messy.

i'll do this.

thanks, gents!

and good luck with that CIS, azzy.... unfortunately, i am no help with that!

So lee dies then. Never used those I use RCBS press and dies. Did the dies come with instructions? I Remeber something about how to set the seating die and a 1/4 turn but thats just for mine.

[svandamme]

David,

so he has to expain the neck to seat the bullet, right
So , he has to crimp it after seating..

So , it should be measurable as to what the crimp actually is?

What caliber is it? .308 ? something else?
For that caliber, there should be a specific crimp measurement, right?

I know for .45 acp , the crimp at the case mouth should be .470-.472
But don't know what his crimp should be , don't even know what caliber he's loading..

[Porsche-poor]

Most dies have a roll crimp built into them that work well for rifle cases that are not auto loaders. For my AR-15 I have it set to not crimp the case while seating the bullet and then run them thru a factory crimp die as a sep. stage.
My 30'06 dies seat and roll crimp in one step. The trick is to find the roll crimp edge then seat a bullert high and keep working the set rod depth after the crimp is made till you get a bullet that is the correct length. If all that makes sense.

[nynor]

trust me, i've been following the instructions.

i played with this some more, case with no powder, and i cannot see that the bullet seating die is putting crimp on the case at all. i adjusted height with no difference.

[Porsche-poor]

its not going to be very visible I don't think. Its a roll or a pressing of the case towards the bullet. If your looking for a sharply defind line then thats a factory crimp for a semi-auto rifle.
What do the instructions say about setting the crimp?

[Porsche-poor]

next post will be the instructions from my dies instructions.

[nynor]

if you want a positive crimp, get the factory crimper.

i figured out what i did wrong. its not obvious. when i set the collet sizing die, it compresses about 1/16 of an inch. this was causing me to read the height adjustment incorrectly and not getting the case neck completely sized. well, i have forty primed cases that i can now size properly and load. live and learn. i will pull all the bullets that i made apart (the ones that i can) and resize the necks.

thanks!

If the bullet you are using has a definite cannelure or crimping groove, the bullet can be seated and crimped, using the following instructions. The crimping feature is machined into the seater body - it is not a special attachment to the seater plug - so the die must be moved up or down to obtain the proper crimp adjustment. Place a sized, primed and powder-charged case in the shell holder and run it to the top of the press stroke. Screw the seater die into the press until it is about 1/8" above the shell holder. Lower the case and insert the bullet in the case mouth. Now slowly run the case and bullet into the seater die. Check the bullet for proper seating depth. If the bullet is not seated properly, adjust the seater plug until proper depth is obtained. Next adjust the die to crimp. While the uncrimped cartridge is still in the seater die, unscrew the seater plug several turns. Then screw the seater die downward until you feel the built-in crimper touch the case mouth. Lower the reloaded cartridge and adjust the seater die down about 1/8 of a turn. Then run the reloaded cartridge back into the die and check the crimp. If more crimp is desired, repeat the proceding step by adjusting the die downward 1/8 of a turn at a time. After you are satisifed with the crimp, set the large lock ring and run the completed cartridge into the seater die and lower the seater plug until it touches the bullet. Then set the small lock ring. Once the seater die is properly adjusted the bullet is seated and crimped in one operation.

the 72 has a 3.0 litre SC CIS engine in it, and as it has been down for almost 2 years, it is not happy, I am thinking that there are vacuum leaks somewhere in the system, but there are so many vairables in the CIS systems, it is so hard to diagnose, so we have started at the beginning and are just slowly going through the system to see where it is not to spec. But it sucks.

Good news though, it has stopped raining, again. But the winds are picking up and it is a bluddy cold wind, so for all you guys in the Northern Hemisphere it must be warming up, as we are cooling down, not that we really heated up for the summer, it was "water cooled".

I crack myself up!!!!!!!!!!!!!!!!

[svandamme]

What are the symptoms?

Rough cold start?
bad idle?
poor part load?
poor wot?
bad warm starts?

[nynor]

oy, azzy, what a headache.

per advice above:

i just got out the cartridges that i reloaded last night. 14 of 20, the bullets pulled right out of the case. i resized them and seated the bullets. all of them are nice and tight.

it seems that the collet sizing die adds a slight crimp to the top of the case. i wasn't getting that crimp at all. i also resized all the brass that primed. when i get new bullets, i'll reloading all of them with non-moly bullets. i read that people use stuff like PB blaster to clean the moly out of their barrels!!! i guess i'll be taking my can of penetrating oil with me to the range....

Not sure about that, Max.
Dave is still on the forum.
The fact is, he is just not posting on this thread.

huh.... what is up with that?

frankly, this about the only thread i post in. the regulars are nice and the topics are fun. plus, anything goes. i do post the occasional picture in the appropriate threads, but that is about it.

[GH85Carrera]

Dave took a vacation from the thread once before. He came back.
Heck master Stijn took a break from his own thread.
