You have any pictures of these oddballs?
Left to right: 1-7/8", 2", factory 2-3/4" (fold crimp), 3-1/4"
Crimped length depends on wad/gas seal pressure, and crimp pressure for the particular load. Left to right (rounded to the nearest 1/8"): 1.5", 1.75", 2.25", 2.875"



The 1-7/8" shell is loaded with a little less than 3/4 oz of shot, and a moderate dose of Red Dot.
The 2" shell is loaded with 7/8 oz of shot, and a "heavy" charge of Bullseye.
I've never chronographed either load, but they should both be a bit over 1,200 fps, while remaining under 9k psi.

Straight hulls are required. Tapered or compression-formed hulls don't have enough capacity, the taper causes wad and gas seal problems, and pressure spikes can sneak up on you.


Load on Sunday, and shoot all week.
