put my chrono at 25 yards so the sabot wouldn't hit it
worked out pretty good
I started out shooting a saboted 420 gr bullet
70 gr Pyrodex 1234, 1251
80 gr Pyrodex 1303, 1308
90 gr Pyrodex 1399, 1390
100 gr Pyrodex 1402, 1440, 1428
so yes I was pleased.
the next load was with some Remington 240 gr JSP and some green sabots. This is where the crazy stuff started, but..it explained a lot, mainly that this combo (bullet and sabot) does not want to be separated, and the sabot was flying through the chrono with or behind the bullet causing whacked out data
70 gr Pyrodex 1511, 1464, 1467
80 gr Pyrodex 1637, 1588, 1637
90 gr Pyrodex 1610, 1680, 1693
100 gr Pyrodex (chrono at 25 yds) 1545, 1367 (chrono at 50 yds) 1672, 1715
so the 420 bullet was cleanly separating from its sabot at about ten yds. not so with the 240 gr pistol bullets, I found sabots at 25 yds and beyond, and it looks like the 100 gr powder load really makes it epidemic
