The Judas Group is controlled by the US military, therefore, Dorudo's sniper rifle is most likely made by the US military. The distance between Dorudo and Ikuro is 913.28 metres, and the situation was described as "A battle fought in a fraction of a second.", "fraction of a second" = 0.9 seconds at the very least.
Speed = distance / time = 913.28 / 0.9 = 1014.75555556 m/s (at the very least)
The events in "Baoh" take place after World War II (The year is unspecified.), by checking this list [ en.wikipedia.org/wiki/List_of_sniper_rifles ], you'll see that, most likely, no sniper rifles that can shoot bullets specifically that fast were made by the US military, and we know that the muzzle velocity of Dorudo's sniper rifle has to be higher than what we calculated. Why? Because the muzzle velocity of a bullet is its top speed, and it decelerates steadily after it leaves the barrel due to air resistance. In that list, the muzzle velocity of the sniper rifle known as the "M40" is listed as 10500 m/s, but it seems to be false because it's also listed as 2550 ft/s, which is only equal to 777 m/s. In that list, no sniper rifles developed by the US military with a muzzle velocity higher than than the speed of the bullet fired by Dorudo's sniper rifle has been found, so I can only say that Dorudo's sniper rifle might have been imported instead, let's check the list again.
Out of those four sniper rifles, only the Steyr and Istiglal are used to shoot explosive rounds because they're anti-material rifles.
Of course, Dorudo probably wasn't using either rifle, but, this is merely something we'd need to work off of, simply as a real-life rough approximation of what he might have used as a weapon because if we don't know the muzzle velocity, there's no point behind this calculation and the feat would be unquantifiable.
As for which of the two rifles is a closer approximation, I would say that the Steyr IWS 2000 is more likely to be so. Considering that, while the year which the events of Baoh take place in is not exactly specified, it shouldn't be sometime close to our present if you consider the train models which have been shown in the story or things like that. The Istiglal was released in 2009 while the Steyr was made in the mid-1980s.
But, all things considered, I think its better to simply take the average of the muzzle velocities of the two rifles so as to eliminate errors in judgement to a certain extent. (1132+1450)/2 = 1291 m/s
Dorudo seems to be on the roof of a 6-storey building, so his position is about 20 metres off the ground (Dorudo was lying down, so there's no need to take his height into account.). The distance between him and Ikuro is 913.28 metres, which is basically 913 metres. The setup here is that of a right-angle triangle. Using this calculator here: ( www.cleavebooks.co.uk/scol/calrtri.htm ), it becomes evident that the angle which the bullet was fired from is -88.7°. For a bullet fired from an angle of -90°, its muzzle velocity and final velocity are almost equal only due to an extremely small amount of drag, but if drag was ignored, then the muzzle velocity and the final velocity would actually be equal. So what will happen is that I will convert the muzzle velocity into a mach number, then subtract a bit from it. Of course, there is a way to accurately calculate it, but the problem is that we don't know the measurements of the bullet and we don't have a time-frame, so we can't use it, and to be honest, considering that the bullet was fired from an angle of about -89°, it wouldn't be much different if it was fired from an angle of -90°.
Another factor would be Ikuro's own height, Dorudo was aiming at his head. Previously, I said that the bullet was fired from an angle of about -89°, that would have been true if Dorudo was aiming at the ground beneath Ikuro, but, he wasn't. Anyway, using this calculator [ rechneronline.de/sehwinkel/angular-diameter.php ], we can figure out the actual angle the bullet was fired from. Inputting 913.28 metres as the distance and 1.712 metres as the actual size (average height of Japanese men) and calculating, it seems that the angular size is basically 0.1°, which means that the bullet was fired from an angle of -88.6°, which, doesn't change anything unless we're considering to use extremely accurate numbers, but sadly, we do not have that luxury for there is too much information regarding the projectile itself missing.
Let's get to the final part. 1291 m/s = Mach 3.763848 ≈ Mach 3.77
The bullet was shot from an angle of -88.6°, so it's extremely close to being -90°, and that point, the final velocity ≈ Muzzle velocity (due to small amount of drag)
But it's not -90°, so I would say that the bullet was moving at Mach 3.5, it could be higher, it could be lower, it's just an estimation.
Ikuro wasn't simply faster than the bullet, he completely perceived it in slow motion and even had time to carefully contemplate his next course of action, so I'd say he's 3 times faster than the bullet, making his reaction speed Mach 10.5 (Hypersonic+).
So how fast is Ikuro in his Baoh form? Well, since his base got much stronger at one point, naturally, his Baoh form would have become much more powerful than before. Pre-upgrade, Ikuro goes from being slightly superhuman to being able to shred metal with his bare hands effortlessly and dodge explosions, and that's only Baoh transformation Stage one, Stage two is even more powerful than that.
So, for each transformation stage, what is the upgrade factor? *2? *3? *4? *5? *6? (and so on.) With his feats in transformation stage one (tearing through a car's roof and avoiding a giant explosion.) you could perhaps even peg it at *10.
But, using low numbers is usually safer, so I'll say that the factor is simply *3, making Ikuro's combat speed in his fully transformed form Mach 90.
(I know, I know, too many estimations. I don't like it either, but what can I do? There's too much information missing. The measurements of the bullet, the time it took for the bullet to cross 913.28 metres, the muzzle velocity of the rifle used, how much stronger does Ikuro become when he transforms, Ikuro's own height, etc. Or else I wouldn't have written this much.)
Dream: Looks like a remake of Higurashi no Naku Koro ni will be airing in July. The original seiyuu from the 2000s series will reprise their roles for the remake and judging from the animation, looks like it will have more polish to it compared...

Taka: 1 confirmed death in my hometown next to 19 confirmed cases. I heard the police are fining folks for not practicing social distancing on Facebook.
Mar 24, 2020 2:31:40 GMT
Dream: At least in New York right now, they're not enforcing it. But non-essential employers who aren't abiding by shutting down at this point will be fined and shut down at this point.

Master Menos: Had some serious personal trouble go on, but now I'm through it. On-Topic, where I'm in, everything but the stores (and possibly the restaurants) are closed down.
Mar 27, 2020 17:48:40 GMT
Taka: They closed off beaches and parks along bike paths as well as extending K-12 school closure to mid May while colleges are cancelled for the semester.

CosmicNoirTear: Everything closed on my part. I live by a bunch of shopping centers. All of the are ghost towns. Hopefully means most people where I live are taking this seriously. Also got laid off from my job two weeks ago.
Mar 29, 2020 2:46:08 GMT
Dream: My county has 6 confirmed cases. Restaurants and bars have been on take-out or delivery only for about a couple weeks now since New York's the hardest hit state. Hasn't been too different for me any who since I've been out of work and tight on money...
Mar 29, 2020 15:11:51 GMT
Dream: ...to do anything outside of getting essentials and job hunting in recent months. Though with the state pretty much on lockdown, likely gonna have a rough time finding any employer to work with in-person for a while.

El_Directo: Stay safe guys
Mar 29, 2020 20:08:55 GMT
Taka: I think the only thing not closed for mass gathering other than essential services would be funerals in my area. The mayor and staff have been pretty busy in clarifying things in press releases. Edit: my mistake. Funerals are closed.
Mar 29, 2020 21:52:25 GMT
Dream: Gonna try whipping up a review for Dorohedoro at some point tomorrow. Find that I have quite a bit to cover with the series.
