Thanks for this report, but unless I missed it, would love to read the cyl. gaps of all 3 revolvers.

Same thing in the rifle world. Some barrels are just faster. Find a fast barrel that shoots well and keep that gun. Exactly. We could care less what the speeds are. We don’t load for that. Accuracy is all that matters then you find out the speed 🤣 we do make sure that our ES is low single digits. If not, try more and then comes seating pressures etc. we have seating pressures down to 4th decimal place now days 😜

Any perceived recoil difference between the guns? Some people claim a shorter barrel recoils more. Others say the long barrel leads to more torque and recoil. For me with the same loads a 10-1/2" Super Blackhawk is a lot more pleasant and manageable than the 4-3/4" version. Likewise for shooting I will take an 8-3/8" S & W over a 4" for the same reason.

I assume you are going for consistent neck tension?

I've had several 4-6½" 44 magnums over the years and found the 4" to kick a little more violently, even though it is Mag-na-ported. It has less muzzle rise, but still more "pop" to the hand. Just recently I acquired a 10½" SBH and couldn't believe how much less recoil it has, even with the factory wood stocks. It's a honey of a revolver!

I assume you are going for consistent neck tension? We group them based on the seating pressures. Adjust the pressures by varying the neck tension yes. Varying sizes of expander mandrels to the .0005 difference and work with it until you find the best combo. We seat them and the rounds are numbered. Then sort the list and grab the matching pressures for different relays. It helps make sure all the rounds you shoot that relay match as much as possible. Use outliers for foulers etc when you’ve cleaned the barrel at some point etc. this is a list after the sort. This is when I first started using this system. Caused me to change a lot of the prep, chamfer tools etc and now the number don’t have the variance of these in this list. Sometimes you can have too much info. But for the long range game, I like as much info as I can get.

Great info, I ran similar testing many many years back- basic results were that my favorite Casull only .45 Colt only loses like 30f-fps dropping from the 7-1/2” guns to the 4-3/4”. When .45 cal. 360grainers are at a nominal 1400fps they KILL. LOL just ask Ross Seyfried cause it’s his “Gould style” penetrator I cast and load using data he provided Jan libreual For ancient guns&ammo article. Running various recipes either from Mr. Dick Casull himself or similar experiments based on his results- certain bullet weights/powders prefer longer barrels for optimum velocity

In this case the 4" is faster than the 6" Have seen similar results, mass produced gun with the various tolerance stack ups involved in multiple critical dimensions often yield suprizing results. Such as 10-5/8 silhouette S&W posting barely equaling the speed of a 8-3/8 version and a 7-1/2 Performance center w/ built compensator equaling both even though the PC gun was typically the slowest gun I ever tested in The 7.5 to 10” class
