BD:
With all due respect, the factual basis for my statement is threefold:
1) About 30 years of experience and tens of thousands of rounds in shooting such loads in "short" chambers of Damascus and fluid steel barrels.
2) Sherman's Bell's tests/report many years ago in Double Gun Journal.
3) Personal consultation with Tom Armbrust.
Okay, and at the risk of being tediously repetitious:
1) About any birdshot load in the 1100 - 1150 fps range. Notice I didn't say 000 buck.
2) I didn't use the word "inappropriate." I wrote "preferable." Because paper is a bit less compressible than plastic that's already skivved. But paper will still work...
3) According to Bell's and Armbrust's pressure-tested work, skivved 2 3/4" plastic hulls add about 25 psi to pressures as opposed to 2 1/2" hulls. Depending on the chamber/forcing cones of a specific gun.
For further insight, please consult Sherman Bell and/or Tom Armbrust...
