Loading with fiber wads

[corono]

Is it OK to put  a nitro card on top of fiber wad to get stack  high correct. What I've got is16 grains of greendot  3mm nitro card 18mm fiber 3mm nitrocard perfect  crimps .firrochi  67mm case

That’s fine no problem

Thank you dipper

Yes but generally  if the column hight isn't enough any additional cards to adjust the hight need to put under the fibre wads.  A thick card over the top of the shot can affect the pattern.  Using  a thin over shot card on top of the shot helps to get a better crimp but not a thick rigid one.  or get thicker main driving wads to adjust.  I use Green dot but in 70 mm cases

Minky 3mm nitro card over powder 18mm fiber wad 3mm nitro card then the shot

or preferably first 3mm nitro card, 2nd 3mm nitro card and then 18mm fibre wad, then shot.

I think that any of the above combinations will work but not fitting a thick card over the shot.  I did get a thinnish black hard card for putting on top of the fibres so that the shot is on a hard layer and doesn't get embedded into the fibre wadding on take off.  But it would be better to have a 3mm overpower card and get thicker fibre wads with the  thin black hard card on top of the wad to stop the shot embedding and a thin, thin over shot card (like the ones with the shot size printed on them.  Sort of 1 mm for a good crimp.  Basically it reduces the amount of individual components which makes it easier to load and costs less. easier to load, cheaper and less objects to load.  Sometimes I get the.... Did I load that card.?

Edit. I'll have to have a look at  what components are on the reloader and that I used. I'll have a look and add a picture or two of the bits albeit that I'm using 70 mm cases.

I have never picked up a fibre wad with shot embedded in it. A hard card on top of a fibre driving wad may result in more lead pellets being deformed on firing due to the set back forces squashing more pellets. Not seen any 6mm nitro cards available so in these circumstances if using the components the OP has i would double up on the 3mm nitro cards then fibre driving wad with shot on top of that. The thin black capping on fibre wads is plastic, but not necessary as Eley used to use wads without it.

It’s like suddenly stopping a car all the contents of the car travel forward, same with the wad, its velocity quickly drops to zero but the heavy shot travels on forward leaving the wad behind.

Yes they were the old eley kleena wads.

Would fiber wads work in tapered cases  like sts cases with a bulky powder like green dot. Having said that alliant  don't publish  data for 7/8 with greendot. To high a pressure cracked alot of tube sets so no publish  data

Used to correspond with David garrard  Home loader from shooting times .I asked him the same question about fiber wads in tapered cases .He said just put a paper wad over the powder then fiber wad

There's some would say load the extra wad as a sandwich between equal two charges of half the total weight of the shot. To get a close range spreader load. Or if you can do so trim the cases down to a true 65mm length and you shouldn't maybe need that extra 3mm wad at all?
