I did not misundertand the question and I'm quite certain of the intent.
A new to me Jost & Diehl Cape gun from between 1874 and 1882 arrived and working with it I've spent more time in my loading room. I sent back the one in 43 Mauser X 16 bore...it just wasn't what I wanted. I found another in what I'm pretty sure is 10.5 X 47R and 16 bore. That's as close as I can find from the chamber cast. the 16 bore is chambered for the 2 1/2 brass or paper hull and has 6 major lands of straight, Henry style rifling and between each rifling is 6 lesser lands of straight, Henry style rifling. I've read of it but this is the first example I've seen. This one is gonna be interesting! I finally found my data from my shooting of the original 43 Mauser loads and 500 BPE loads. After 3 moves since I did the shooting they were kinda MIA.
43 Mauser, dated 4 September 1995
#1 - 1390 fps
#2 - 1396 fps
#3 - 1427 fps
#4 - 1402 fps
I have a question mark next to the 1427 load but do not remember why. I suspect because it read so much higher.
500 BPE, I did not write down the date but suspect summer or early autumn of 1997 because I got my 500 a little over 2 years after the 43 Mauser.
#1 - 1799 fps
#2 - 1810 fps
#3 - 1788 fps
I thought that pretty close for what was 100 year old ammo at the time.
I didn't find the 400 BPE data and I expect I gave it to the owner of the rifle.
