At very low pressures does the brass even deform?

I had a 600 JR 10 I bought new and it worked fine . But later I decided I wanted a Sizemaster with the collet resizer and that’s what I use now . I had a PW 375 many years ago set up for 10 gauge 3 1/2” that worked very nicely . But what I’d really like but don’t really need is a PW LS-1000 set up for 10 gauge 2 7/8” .

The 600jr will resize the brass properly but I found the hulls are difficult to remove from the die. I resize my 10ga hulls on a MEC Super Sizer.

If you remove the resizing die, you can loosen the nut, lengthen the depriming shaft and the hulls will just pop right out. Don't forget to retighten the nut on the depriming shaft when adjusted.

With Cheddite hulls being the only current option at BP or PR and Red Dot being out of stock at both places as well, what is a workable 1 1/8 oz 10 gauge load?

Look at 12 gauge 1 1/8 ounce load data using Unique , Green Dot , WSF , WSH . I’ve done this without issue just going by the charge weight , however you’ll have to mess around with spacers to make the shell full enough to get a decent crimp . I’ve had good luck with 16 gauge card or filler wads as well as dried red beans you buy in the grocery store . Some folks use Cheerios some have suggested sliced up packing peanuts .

Good Lord, what have I gotten myself into???

The cheapest 10 gauge hulls (in fact the only 10 gauge hulls available) were $62/100. That's the equivalent of over $15 a box for the just the primed hulls!

Not to mention the 10 gauge reloader, short kit, case trimmer, etc. etc.
...and a chronograph to check the loads, since there are no tested loads for currently available components.

Oh, and there are the two Parker 10 gauges that started this whole journey.

I think I need someone to conduct an intervention

Actually, to be honest, I am really looking forward to experimenting with developing a target load for these guns from the 19th Century, and then perhaps a bismuth load for ducks.

As I do, I will share what data I have with those of who are obviously devoted to this bygone gauge.

Thanks for all of the advice.

I took a block of oak bored a 10 gauge hole thru it and made myself a little jig sorta thing to trim hulls . At the time I was trimming maybe 300-500 at a time all REM hulls . Then two or three years ago a friend made me a trimmer that works by hand using a box cutter blade , takes a bit of effort with REM hulls but it’s pretty slick with the Cheddar Cheese hulls which I use more of now . Let’s see with 10 gauge stuff I’ve loaded I’ve done in clay targets , dove , quail , pigeons , partridge , pheasants , squirrels and deer .
