Well, I tried 4 different paper thickness patches with 120 grains by volume Pinnacle 3Fg, in the Disc Elite 45cal with the powerstem plug..Results are in:

Big Fat Failure [:'(][:-]

Main problem was the sabot blew past the bullet--left a clean hole right through the Base of the sabot. Ened up KeyHoling every shot
So I improvised a type of "sub base" by cutting the petals off a spare sabot, and loading the cupped base first, then the loaed sabot. Shot about 5 of these and still keyholed.
Then I added a balled up piece of cleaning patch on top of the improvised sub base, then seated the loaded sabot on top of that...result was a horizontal keyhole dead center of the 30 yard target [&:]

I guess this combo just can't be spun up right with my 1 in 30 twist rate. Or the .348cal bullet needs a stronger better fitting sabot

So I changed breech plugs to the Standard plug and tried 100-90-80-70-60 with same results with all 4 types of patched sabots. Then I tryied 50grains and finally got stabilized.


However, my high speed hopes are dashed! I think I'll try once more with a really tight fitting paper patch, but I'm not hopeful. Perhaps the 200grain bullet is too long for my twist rate.

Guess it was a good thing, that I forgot to take the chrono
