My .60 cal Tri-Ball Load Results
Ok here’s the deal from the OP.
The load that generated that pattern was 3 1/2” with 32gr STEEL. I use 3” hulls with 28gr Blue Dot just the same. Both are roll crimped. Both have 1/4” cork or fiber in the bottom of the wad. An overshot card is not enough to protect the base of the shot-cup. Both use PSB. These loads were taken straight from info I gathered on this forum by James and RMC iirc.
That pattern is typical of my A400 with my .680 choke and 60 cal balls. I tend to get my best results with the 3 1/2” version, which also requires 1/8 or maybe 1/4” cork over the shot.
I doubt .575” balls will ever work well in this wad/gauge combo.
Patterns that you say are blown and wads that are shredded are due to a choke that is too tight. .670 choke diameter never patterned well in any of my guns. Damage to the base of the wad cup is due to lack of cushion...use cork or fiber wad (or maybe felt), OSC is too thin.
One of the most crucial steps is to split the wads as far as you can take a sharp pocket knife to the shot cup. The factory slits are not deep enough and will not release the bottom ball properly, often upsetting the entire shot or carrying the wad straight through the target (or animal).
Open the choke up. Your results should improve. These petals are .035”-.045” thick. Do the math and you can see why the recipe and recommendations are pretty specific.

I’m using a standard Lyman vibratory tumbler.
Those .575 balls are what you need for 20ga, from what I can gather. I wish I had some bc I would love to eliminate these 2.25oz 12ga payloads.

Yes they did start at .570. I’ve seen those posts in the past.
If I were to chase the .570 / 12ga combo, i would definitely find a way to align those balls in a straight column inside your wad and stabilize with the PSB. Maybe thick mylar or teflon wraps will do the trick. Mylar is much cheaper. I would also keep the same concepts that we’ve been using with the .60 cal balls.

20 inch slug barrel with chokes??? 30 yards. Hmmmm.
If those are 60 cal, thats more than 1.25” center to center.
