So, herein I publicly admit my failure.
I have a 40 cal mould made by Accurate moulds that I bought for shooting in my 45 Paramount. I used the Harvester Crush light blue sabot and from 85 to 105 grains of Blackhorn in 5 shot "groups". At 100 yds I couldn't even find where most of the bullets impacted on a 3' square piece of cardboard. I sent my Paramount away to have a Brux barrel installed, so my testing has ended. I still think this bullet and sabot has great potential. I cast the bullet of scrap lead, it may have a bit of tin and antimony in it . Brinnell hardness was about 9 iirc.
My range is kinda overgrown so I didn't use my 25 or 65 yard bunker, I went straight to the 100. That's a mistake. I use an 8.5 x 11 sheet of paper as a target with a 1/2" square aiming dot. Some bullets hit the paper, most weren't found so I put the 3' x 3' cardboard sheet behind the target stand. I never found where some hit the ground. They completely missed the 3' x 3' cardboard. I found about half of the sabots fell off the bullets about 20 ft from the muzzle. I found 2 at about 70 ft where I know they went through the skyscreens of my Oehler. I dug into the dirt of my bunker at 100 yds to search for bullets, expecting to find the sabot still attached, but my digging turned up no bullets, so I didn't confirm my thought that the sabots stayed attached.
Whenever my Paramount returns, I'll continue this testing, with smokeless VVN120.
