good morning all, hope everybody is safe and well.
I've posted another thread on here regarding overpower cards, but thats run off in a tangent (mainly because of my stupid questions) so thought I'd start a new one as I'm in desperate need of assistance.
The current set up I have got are as follows:-
Various 70mm eley, rose gold and RC HPF3 hulls.
Lee Load All 2
Alliant Herco powder
CCI 209 primers
18mm fibre wads
No 7 shot
The main issues I'm finding is that I didn't realise the Load All wasn't designed for fibre wads, but various members have told me they have loaded them fine, and I would like to continue this from an environmental point.
I'm also aware I need overpowder cards or wads so I'll be getting those.
My thought train so far is that I've used the data from the Alliant manual for 2 3/4 inch Fiocchi hulls, and the grain range dependant on wad (as fibre isn't listed) is between 25.5 and 26.
I've test loaded (with used primer) an Ely Hull, loaded the powder, inserted the wad, loaded the 32g of no7 shot and have a gap of 9.6mm between the top of the shot and the crease line in the cartridge, or 18.2mm total distance between the top of the shot and the opening edge of the cartridge.
My questions are, are the grain assumptions ok as ive gone with the .180 insert in the Load All which should give a projected 26.3 grain, but after several weighing checks is coming out at 24.7 grains. And do I have to make the 9.6mm gap up with overpowder cards/wads as this seems a large gap to me?
Apologies in advance for all the questions but I'm a total newbie at reloading and have scoured the net and manuals etc, but just feel a bit more confident with your expert assistance
