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.
