At 850 yards, the 50 V-Max from a 223, and a 175 Sierra MatchKing have the same trajectory, and at 1,000 yards, the 50 V-Max has only 10% more drop - so why is long range OK with the 308 and not OK with the 223 and 50gr V-Max?
There is no problem with "subsonic" and "transitions"... these are myths passed on by guys that haven't shot at very long range.
There are a fair number of guys on this site that have whacked PD's at 1,000 yds and better with 223 class rifles, and 50gr plastic tipped bullets - all you gotta do is adjust for the (predictable) drop.

Not consistently at all as the bullet at 223 velocity would be subsonic and the transition would likely play helll on which way the bullet wants to go. Yeah, maybe 1 in 50 might hit the target but not the right tool for that shooting.
Sorry Amigo - that is a myth that is believed by guys that don't shoot at long range, or want something to blame for their lousy shooting.
Bullets do NOT change directions.
And nothing "... plays helll on which way the bullet wants to go."
The turbulence is always behind the bullet (like the wake of a motorboat), so the bullet can never go through it... so it can never be disturbed.
That is not "my opinion", it is plain ol' physics.

I do shoot long range actually. Out to a mile at least once a month and 1200 regularly. I see bullets that will not keep it together like the 168 amax in a 308 at that range but the 155 scenar and 175 smk do just fine. In my 6cm the little 115 dtac transitions well. There are different sides to this debate with ballisticians like Bryan Litz confirming what I see and some with smaller names on your side. I guess all I can claim is what I see when I shoot regularly with big names seeing the same thing to support what I am seeing. I guess where you shoot there are different magical forces at play. With the nose up on a bullet when they transition the pressure is not the same on both sides of the bullet. Like I said, some make the transition others dont. I have read both sides of the debate and come up with what I see to be true actually out shooting steel and paper at certain ranges. If what you say is true then the guys running 308 at our matches should have no problem hanging in there, but once the targets venture out past 1000 the 308 for the most part drops off unless running certain bullets and if they get to 1200 the 308 is no where to be seen in the winning circle. I have read the arguments over and over on this and this is as far as I am going to argue my point. To anyone reading this debate I encourage you to go out and run some distance and see what you come up with. Even the experts have 2 sides to this fence.
This is a different discussion that your original comments. Your original comments defy the laws of physics... and Brian Litz also has some revisionist versions of the laws of physics.
I'd love to see any of these guys write this stuff and present it to a university sometime. If they are right, they are in line for a Nobel Prize in Physics (worth about 1.3 million USD).
