Hey guys, had an idea. I was thinking about ULR shooting, and i decided to design a new cartridge. Wadda ya think:
Caliber: .458
Bullet weight: 550gr-600gr
Muzzle Velocity: 3,250-3,500fps
Ballistics are better than the .408 Cheytac, .50 BMG, and .416 Barrett.
I originally decided to base it off the 14.5x114, but then i learned about recoil impulse. So i am thinking a 20mm Hispano or a completely new case, somewhere between the BMG and the 14.5. Any ideas?
I know that this doesn't fill any niche, or fix any problem, i do this for fun. I can get .458 match bullets meant for the .458 Steyr, so that isn't a problem. Tell me what you think!
Thanks,
gvn
P.S. does anyone have a link to the hispano's case dimensions?
