I’ve done considerable thinking on subject of straight cases since now legal Ohio deer gun.
I had 45/70 when laws came out and promptly got 44mg and 375Win. I decided the 375W was the one to get the most out of. I’ve now thinking sweet spot to be .40cal.
That 400AR I referenced in an earlier post sounds like it woulf fit that 40 caliber size perfectly.
They started they tests with 200 gr .40 cal muzzle loader bullets and after a number of tests, they reached the set goals.
The .400AR final load launches the 200 gr projectiles at a muzzle velocity of 2,312 fps with 2,374 ft-lbs of muzzle energy (at around 50K PSI of pressure). It also reaches pretty interesting numbers with .40 cal handgun bullets. Particularly, it pushes the 135 gr bullets at 3,042 fps.
