That brings up a good point.
The ever elusive case filling of big cylindrical cases with mild(er) charges.
This problem isn't limited to revolver cartridges either.
Most of the former black powder and cordite rounds have struggled to find a proper case fill
with nitro powder that also comes in under the rated pressures and gives desired performance.
I have played with my share of inert case fillers in just the limited rounds I shoot.
Although not listed, I am leaning more and more to the new cowboy powders for this reason.
Case fillers add another sometimes dangerous (now) unnecessary variable to the equation.
As an example; a favorite 44 special target load was 4.5 gr. PB with the case filled with 9.5 gr Grex under a 240 SWC.
This gives about 650 fps and blows the case out to a full seal.
I can easily duplicate this with Tin Star or Trail Boss without the filler.
Still working on the fine details for the various guns.
I obviously don't mind heading to the range with the chrono and spending a couple 3 hours shooting some tests.
Another main objective when I shoot is to create empties so I can reload some more
