I reviewed the Mantis system at the SHOT Show 2023, it does what more expensive system do for less cost. The increased trigger prep, trigger press, and result for less the cost of the ammo will offset the cost of the ammunition. One of the things I pick up on You Tube; people that always shoot from the bench are hard pressed to shoot well from an unsupported position. The bench tests the ammo, and the firearm, there is little testing of the ability of the marksman. I frequently officiate bench rest matches, little or no contact with the shooter and the firearm except triggering a 1 ounce trigger. F-class competiton is shot from the prone position with either an extremely expensive mechanical rest or a rest (some mechanical) attached to the rifle (depending on the class). F-class does require interaction/body contact between the shooter and the firearm.
