Will I still be able to get the slugs in the cases?
Bolt gun = cheating! Use a Winchester 97,
from the hip
The CBC case internal dia is approx 11-bore
The sabot slugs are under 12-bore dia. = there IS some
"wiggle room" as the slugs are under sized & most of the plastic wads you'll find are going to be 12-bore specific. The plastic wad is what the slug will ride down the barrel in...so it has to be a good fit in the wad.
Dangermouse wrote:I hear a lot regards sabot rounds and plastic wads, any thoughts on accuracy with these? Accuracy is the name of the game for me.
THE wads to use are the Federal 12S4 - or as close as you can find to them. As you are using the slugs in a brass case, the wads will need to be 11-bore...SO, it may be a case of using a plastic wad as a sabot for the slug, with a felt-wad below that as a gas seal
Dangermouse wrote:Do the cases not need resizing? or just trimming from time to time.
Once they are fired, that's it. They are then fireformed to your chamber
You'd only need to trim them IF you decided to taper crimp them...so best not to, as there's no need to
Dangermouse wrote:I guess that you still need some kind of shell holder to seat the primers, do you recommend any?
The main RCBS Cowboy die set you linked to DID have a s/h included...though MidgayUK also stated that the dies were to be used to remove the large rifle primers from the brass. (The CBC box states LARGE PISTOL primers)
You can just seat the primers on a flat metal surface. Align the primer into the pocket, rest the case above it & tap down from the inside of the case until the primer is flush.
Honest!
Never seen one of the old Lee Load All shotgun sets?
That said, IF you don't want to do this stage & cannot get the M-I-L to do it, I
may have a spare s/h I can hire out at very reasonable rates

Water glass, a.k.a. Sodium Silicate. I got a litre online, delivered, for just over a fiver.

Dangermouse wrote:I assume that a wad has to be used to compact the powder, to assist with consistent burn rates, even when using slug? Is there a gap between the top of the wad and the slug? or do you have to push the slug down to sit on top?
Use a wooden dowel to firmly press the powder wad onto the powder, EVERYTIME - no matter if making slug, buckshot or birdshot loads. NO air gaps = dangerous & bad for pressure.
Over the powder card it is best to use a sealing wad, felt is good for this, THEN the payload
(slug, buckshot or birdshot) THEN the overshot card, sealed with water glass.

Do what I did
Read EVERY article & write up on the net, i.e.
http://www.riflemagazine.com/magazine/P ... artial.pdf (page 48 onward)
Then read them all again.
Then look for more stuff to read, buy old manuals...and the new ones. BPI offer a book dedicated to brass shotshell reloading. Look on the Circle-Fly website. THEN re-read everything a couple more times, then get the kit together & go for it
