.45acp, 200gr cast bullet, 231 Powder How low Can You Go?

Today at the range I was shooting my Gold Cup. I was using 5.4 of 231 with a 200 Grain Cast SWC. Best target of the day is below. Not shabby for a shakey old guy. Oh, to be 30-35 years younger!!

My accuracy load with a 200 gr Cast SWC is 4.3 gr 231. I tested many loads with a Ransom Rest at 25 yards and this load came out hands down. I can shoot it all day and not be bothered by recoil.

Ransom Rests are fine. A friend has one and we have used it. We both prefer shooting off hand as it gives us a better feel for what the gun, load and shooter can really do with a specific loading.

I don't love 231 for reduced loads either, but I'd be willing to go down to about 4Grains.
I ran an awful lot of 205s pushed by 5grains of red dot, because I had a lot of both.
Lately I've been running 4.6of WST behind a 205 with better accuracy results and haven't had any function issues with factory springs.

I've been using 4.4 WST behind a 200 grain SAECO #68 copy. Very good accuracy at about 800 fps MV. I don't change out springs. Standard ones are fine.

4.2 to 4.4 grm. 231, reduce recoil spring, great for 25yds. ISSUE -- filthy stuff.
Try 3.8 of n310.

It's gunpowder; they're all dirty. Cast bullets add to the "dirtyness" but as long as accuracy is good a little bit of dirt is easy to live with.
Regardless of the degree of dirt, the effort required for cleaning remains the same.
