Yes sir, it was a late fall new release from Hornady. Has a BC of .290 It has the tiny little boat tail like the 40 and 50 Vmax and is actually longer than the 55Vmax. It's a pretty cool looking little bullet, has a very short bearing surface and a very aggressive, long taper. Take a look for yourself.
I'm in the serious thinking process on getting another AR upper built. I love my 223A.I. but it has a 12 twist and I want a bullet to reach out to 500 to maybe 600 yards with authority. Been contemplating the 69 to 70 gr. 224s or maybe the 6 TCU. I just don't think the six will get er dun. My 223 A.I. now shoots 55s to 22/250 velocities (chronoed) and I think I could reach 500 on PDs with it. Just thinking about another one with an 8 or 9 twist for a heavier bullet. As to your predicament; I really think the 223A.I. with a 9 or 8 twist will do everything a 22/250 will but without the recoil,extra powder, blast, and barrel erosion. Just my 2 cents.
Iv been tryng to find a 223 with 1-9 twist so I could then make it ai. If not I may get the 22.250 with 1-14 and rechamber it to 22.243 so I may be able to get away with a heavier bullets with all the velocity.
