Milo, can you give me your speeds and come ups? ( and scope height)
Sorry, I really want to get some good numbers on this bullet!

They shoot well. 43.1 g of H4350 and I had a 7.5 mil come up at 1000 yards down at rifles only. I bought 2000 in total.
Also midway runs sales on all kinds of things don't overthink it
Geek, what did you come up with for an estimated bc?
I just used the .274 G7, but the speed does not match up to chrono speeds. I mean that's pretty common even for my 140 hybrids. I'm running a 2860 fps dope on rounds that chrono 2820 all day long.
In my world, that means the bc is higher than what you programmed in????

Also I am curious to know how much faster these run versus the 140 hybrids from the same tube.
Even though they're 4gr less, they have way more bearing surface, IMHO, no way. The 140 will still rule, in speed and bc.
I found that interesting also. The bearing surface of the 136 scenar L and hornady 140 amax are almost identical where as the 140 hybrid is almost .100" shorter! I would equate less bearing surface equals less pressure and higher velocities.
Matt, I respect your posts, as I do geeks, but less pressure really has to mean lower velocity, but put more powder in to make up the drop in pressure and velocity and attain equal pressure, the 140 will rule. His test isn't linear, the only thing straight across the board is his powder charge????
Think of it this way, you build a new gun, find a load, then decide to moly your bullets, your velocity will drop because of loss of pressure. But, up your powder charge to get back to the same pressure as before, the moly bullet will most likely exceed the non moly in velocity.
Maybe I'm confused here. Wouldn't an identical charge with moly vs non moly the Moly would produce a higher velocity? I thought the whole premise with Moly was that you could drop your powder charge and achieve a higher velocity. Meaning if you upped your charge your velocity would be that much faster and if your charge stayed the same your velocity would increase.
Great data/video.
2930 seems real fast for a Creedmoor. Brass looks clean? No extractor marks?
I did get almost that fast with Re-17 and had no pressure signs. I stuck with my 42.5gr H4350 because it just shoots.
So it is .545G1/.274G7? Has Litz published any recordings yet?
Almost looks like one of bergers vld's![]()

So far, so good.
With a BTO of 2.130", the COAL is 2.800".
More testing at distance to follow.....I only have one box.
