John Boy,
In answer to your questions:
Case length of either the WRA or UMC = 1.880"
Length of the pulled bullet = .90"
Thickness of the wad = There was no wad in either cartridge.
The bullet is crimped above the 1st driving band.
Original .45-75 Cartridge dimensions:
2.24" Cartridge OAL
1.88" Case Length
0.36" Bullet protrusion (2.40"-1.88")
0.90" Bullet length
0.54" Bullet seating depth (.90"-.36")
Powder settled but not compressed - .34" from case mouth (solid head button pocket case).
Powder Density - I have not checked but will compare to Goex, Schuetzen and Swiss and post
the result in the next few days.
If bullet was seated 0.54 ... it would be crimped 0.06" above the driving band
That would be about right .......closer to .04" using the 1.88" case.
