So going from some info given from my last post and researching my manuals I made up 3 loads using standard Starline brass and trimming the flex tip
to be flush with bullet giving a 1.590-1.600 COL using the crimp groove.
The loads were shot thru my Bisley BH with 5.5 barrel and speed data recorded with the Magneto Speed unit.
The shooting distance was 20 ft. from the 6x6x16 Clear Ballistics FBI certified gel block and outside temp. was 46 F.

All loads completely penetrated the 16 inch block with Load 1 stopping in 2 1/2 magazines in block backstop. Load 2 stopped in the first magazine and 3rd load in 2 magazines

Load 1 was 9.5 Unique
Load 2 was 20 gr. of Alliant 2400
Load 3 was 22.3 gr. of Alliant 2400

Load pressures? The first load should be within 14000 psi according load data from similar 200 gr. JHP loads.
Loads 2 and 3 most likely in the Ruger only range. Anyone with access to Quick Load could run the numbers but I didn't notice any issues with case removal.
The primer was just a bit flattened on load 3 compared to the other 2 loads.

From my results I like the Test Load 2 with about same expansion at a lower speed. Expansion was .650 with Load 2 and .665 with Load 3.

I do have many other loads of 250-255 gr. lead RNFP and SWC plus XTP 250 gr. bullets for most general uses for my .45 Colt revolvers SA and DA. but wanted
to try a 200 JHP to see results. With bullets hard to come by or on long delays I was happy to find the FTX bullets on the shelf at my LGS. Bought the 3 boxes of 50 each he had. Not much else there.
Going to try that Load 2 in my Henry 45 Colt Carbine too !

Here's some Hornady data I used to get a Alliant 2400 load... Hornady list the 250 gr. XTP in the Ruger Only load data at 19.7 for a start and 20.8 for a Max.
So figuring the 200 gr. FTX at 50 grs. less weight I started at 20 gr.
The 240 gr. XTP Mag bullet starts at 20.4 gr.

There are formulas to figure pressure from the speed and bullet weight but a lot of math and things to accurately measure.
I believe Quick Load program has a plug the numbers in formula for it.

Going to try the load with 9.5 Unique and the 20 gr. 2400 thru my Henry .45 Carbine and the little Rossi Ranch Hand this afternoon.
Very possible the Unique load may pick up some speed thru the rifle for better expansion. 1250 FPS could be the sweet spot!
