Most of these have not been out for too long. The sabotless use 40cal 240gr has been but would not shoot in sabots. They made a version 2 that is supposed to be sabot friendly but will need a 1-22 or faster twist

.451 165gr MZ with sabots
MAXIMUS 40cal.(.400) 165GRH.P
MAXIMUS 40cal.(.400) 240GRH.P. with sabots
They offer two in .429 also. A 210gr and a 250gr.
Some of these will certainly require a faster twist that what is commonly available and some are very pricey. The .429s and 40s are pretty reasonable.
Next Friday one of the guys on another board is gunna verify the 240gr 40cal will shoot in sabots. Im still a bit skeptical but i hope im wrong. He will also be shooting the 40cal 165gr at SML speeds.
Just an FYI i have no connection to CEB and i have received nothing from them either free or bought. I get no discounts for mentioning them or mentioning any forum if i decide to buy some.
