Note: Adjust the numbers as needed for actual dimensions.
Looking at that bullet in the case, you might want to push it in just a little more if you are shooting without a gas check.
Ok, so lets say you go for a 2.08" for your AOL.
Lets say your case length is 1.600"
So this works out to 2.08 - 1.600 = 0.420" exposed bullet.
The drawing of your bullet says 0.773" for length (it will be different with / without check).
So this works out to a seating depth of 0.773 - 0.420 = 0.293"
At an AOL of 0.208", 100% fill is when powder fills up the case to 0.293" below the mouth.
And 90% of the above is a good starting load.
For my 200 gr loads, my notes say I stopped at 22.1 gr of WC 680. I was seating deeper than the above.
I ran Quickload based on the estimated numbers above. Note that some of the calculated pressures go well above the SAAMI 40,000 psi limit. This is ok for your gun, but would not be recommended for all guns.
Code:
Cartridge : .357 Maximum (SAAMI)
Bullet : .358, 195 gr x 0.773”
Seating depth : .293 inch
Cartridge O.A.L. L6: 2.080 inch = 52.83 mm
Barrel Length : 14.0 inch = 355.6 mm
Powder : Accurate 1680
Predicted data by increasing and decreasing the given charge,
incremented in steps of 0.8% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
