I was at the range this morning.
Among other things I was test firing some 300 Blackout bullets I loaded.
125 grain bullet. Normal factory bullets are 150 grain, 110 grain (2360 fps), and 220 grain (subsonic, 1000 fps).
Gunpowder: Loading a little aggressively - Max + and Max ++. Using Winchester 296.
The 300 Blackout is like a 44 Magnum with a handle, in rifle form ... about the same amount of powder. They use a Magnum pistol powder for a case about 2/3 the volume of a 5.56. A little over a cubic centimeter. Not a lot of room.
Loading by Volume because my scale crapped out and I'm waiting before I spend $$$ on another one.
So all I expected was decent shooting at 100 yards. And a serious bullet drop at 200 yards.
Instead, it shoots flat at 100 yards - and up about 1 1/2 inches at 200 yards. I set the scope so that 'zero' is at 100 yards.
It's like stepping on the gas and your 4 cylinder sedan is behaving like an AC Cobra.
The Max+ bullet was loaded to the shoulder, so, a little air-space.
The Max++ bullet was loaded above the shoulder - no airspace. Though it had more powder, it appears to shoot slower, less flat.
Completely mystified.
The lowly 300 Blackout is shooting flatter than factory 5.56 55 grain bullets (which go about 3200 feet per second.)
And flatter than the 308 (150 grain bullet @ 2800 fps.)
Now I want to load 296 powder into my 308
