Pretty impressive balistics, I thought My savage10ml was a bad daddy, pushing a 250 grain shockwave at 2350.
That said Im skeptical that many ML bullets, let alone sabots currently being made, can handle that kind of velocity.
Take a look at this 250 gr bonded shockwave, I dug out of a doe last year. I only load it to about 2000fps, I cant imagine it would have held up at 3000fps!
