That looks like a real proper job. Very smart and look strong enough to do commercial production.

Superb machining... well done I am sure you could sell them if you were able to do a small production run, wish I had that skill!👍

It's a possibility if there were enough demand, I am sending them to Impala59 and we need to see if any changes are required.

Now that I`ve suddenly realised what is meant by a sizing ring and congratulate Tightchoke on his superbly machined items, I attach a photo of my very amateurish and crude hand sizing thingy that I made to resize some 16 gauge paper cases.

It may be crude, but it does work. The bevel edge was obviously necessary so as not to damage the case.

After a period of shift work and sporadic sleep 😩 I thought I would bring this up to date. Firstly, and to quote:

My original remit was to be able to load short runs of 10 gauge in 3 1/2" (Mag 10) and 2 5/8" ( Flues S x S) this because, while I collect all things Ithaca, I see no point in cabinet queens and rotate through my collection constantly. I regularly load 12g on my old Lee Loadall, primarily slug and buckshot for competing in PSG, I get good consistency and felt that I could perhaps utilise the old clunker for my 10g. My findings as follows

The 12 g de-capper (with sizing ring)  will jam with a 10g hull, no surprises there really

De-capping the 10 is now done with a spare parallel punch and a smaller ring to support the base. I will make a centring guide from wood or nylon to ease the operation

Sizing is carried out with the new sizing ring, using a length of oversize tube to push down. If I get any difficult cases I will add a T bar

Primer insertion and ring removal is standard Lee practice, the 10 will sink into the spring-loaded receptacle easily. The sizer returns the case to exactly factory spec.

I found that my tapered 10g shell holder, which came with the roll crimper, fitted in the central position perfectly, but , after removing the 12g wad guide, the 10 quite happily stayed in place for the powder and shot delivery. (I manually built the fibre wad column (including tamping down with a 1/2" dowel with increments, as I was using a fairly soft (for a 10) load of 19.8gn red dot over a cci 209 primer, gas check, 10mm fibre wad, fibre (cut)shot cup, 1 1/4oz 7 1/2 shot, filler, card overshot and roll crimp)

 I went down to my garage to use the pillar drill for the roll crimp

So basically, I can use about 50% of the functions of the 12g Loadall and can  produce acceptable cartridges in 10g for a fairly low start-up investment. Once again thanks to Dave (Tightchoke) for his invaluable input into this project. Next in line is to make some 2 5/8" for the old girl of the collection, I have been using little skeeters 12/10 adapters up until now, it will be nice to stoke a proper 10 load for that 108 year old!

Good morning Roland, glad you've finished that horrible shift pattern.

It was great to be a part of this process and to bring your drawings to fruition, very happy that the system works.

It will be interesting to see what sort of pattern those shells throw.

Make good use of the spare one".
