First Attempt

How about trying this recipe on some used shells leaving the old primer in? You can reclaim the components once you know if they're any good.

I do have some used shells but they were fibre, will that matter?

So, to me, this looks like the best crimp I've done so far. To get it I added a 2mm cork card on the wad and then the shot. I don't like adding things to a recipe without having verified data, will this card effect pressures?

 

 

I think I may need shorter cases.

It wont matter but might give you an insight into how your machine will crimp a shell that already has crimp lines to follow.

[sitsinhedges]

The filler will only affect pressures as much as it's weight but I wouldn't worry too much. I wouldn't use a shorter shell I would use a longer wad instead because having more space in the shell is good for keeping pressures lower. I think a shorter case is more likely to result in higher pressures because there is less space for the expanding gases to expand into before the crimp opens.

So here's one from a used shell...

 

 

Haha I wish. This is what actually happened.

Are you putting the 1 cent coin on the crimp and redoing as suggested?

I tried it with a 5 pence coin and then a 1 cent coin but all that happened was the case began to buckle near the base. With the addition of the card which resulted in a goodish crimp can my problem be put down to much space above the shot?

If there is space for a card inside the shell why isn't there enough space to do the 1 cent coin trick without one? Certainly a spinner would sort them out.

[pestcontrol1]

Have you got the press set up on the edge of the table so that the handle can do a full movement so your final crimp tube touches the base of the press ?

It looks to me as if it not getting a full down ward stroke hence not pushing the crimp deep enough.

 

when you do your pre crimp press and hold down for a few seconds then do the same on the final crimp

This is going to be a stupid question but should the coin sit in the centre of the crimp with a small bit of the cartridge surrounding it? Or should it completely eclipse the cartridge? Struggling to explain what I mean so took more photos.

The load should"t need a card in it

I did have it set so when it bottomed out on the press it just touched the edge of the table. I moved it forward a couple of days ago so now I can make sure I get the full length of compression. I hold down on the pre crimp for a few seconds so that the plastic doesn't move and then do the same on the final stage. If I push down to much the case just buckles at the base?

[pestcontrol1]

Thats the wrong coin it ment to sit just over the crimp

I think it was a one cent euro i cant remember now it went when i sold my lee

So is it the case being too long? I need to go back and confirm the length of case I should be using.

The Mec reloaders have an adjustable punch inside the second crimp station which comes down and forms the recess. I assume the 1 cent coin is trying to copy this operation so it should be of a size that would drop into the recessed crimp on a normal factory shell.

[deershooter]

I think this is the wrong way round use the same powder but 28 grams of shot use the 10 cent coin it should be perfect the column hight seems to high for me ,as for putting pressure on a plaswad that should not be necessary with less shot the load will be safe .

 

I looked the wad up on siarm it appears it's for 28 gram load not 32

 

The coin should fit inside the crimp on a factory she'll not cover the top as yours does

That's an American cent you want a Euro cent I think.

Okay, that makes sense, I was thinking this coin thing would only work if it was a bit smaller.

 

Now I need to hunt for some exotic change.

 

Thanks again guys, can't believe how helpful everyone is, I really do appreciate it.

if you ant got a coin to fit try a washer that fits but if the components are not right you wont get a good crimp

[Floating Chamber]

A washer that fits into the crimp 'cavity' is what I used. It is flat, surface to surface and gives the super glue a good pair of surfaces. Mine has been in situ for twenty-one years.

Cookoff13 do you have a link where people can buy them ?

i actually bought 5 a year or so ago. i gave most of them away. i only knew about this from a very goo friend stateside. (for mec single stage)

another chap over the pond sent me the same style deep crimp punch for my 9000. i think i sent him a few wads to look at. (long time ago)

 

it is labelled as 12LT or 12 long thread.

Cyrus, don't go off on the coin thing yet. Re my post 42, I was trying to show you how critical depth is and can be raised a bit if necessary with the aid of a card, sorry, it wasn't meant to be a suggestion as you don't have that situation.. As I said in the last paragraph, I think you have a 28-30 gram wad. Its going to sit too high up in the case and 32grms of shot won't fit in. You're trying to fit a quart into a pint pot!! So as you bring the press down, you are trying to fit 32grms into 28-30grm space, hence the crushing.

 

Deershooter post 67, thinks the same. Take his advice on a lesser load of 28grms and try one at 30grms and see what you have. One of those two will be right for that wad, within a tad, then you can fine tune. The pic of mine in post 42 haven't been coined!!

Okay so I decreased the load to 28grams for the middle cartridge, not a nice crimp. I then did another cartridge (the one on the left) and dropped 30grams, crimp's not much better than the 28gram one. The cartridge on the right is one with a 2mm card in the bottom of the wad, I think the crimp looks pretty good.

 

 

So what does that mean? It's like the wad is too short, 32grams isn't enough to fill the space or the overall case is too long.

 

Thanks again for all the input guys.

Personally i'd load them up like the ones on the right and shoot the things!

 

Its nice to have a neat crimp, but if the cartridge goes bang and kills stuff what is the problem with a slightly mucking looking crimp? Most of my fowling loads have a dodgey looking crimp but they go bang and kill stuff
