What is the the most flat shooting cartridge yall can think of?

[Phil Rizzo]

I've fired 3.5" shotguns that were worse.
It's more of a shove than a punch, as it is now.
If it was maxed out with 400gr bullets I suspect it would be all the above.
Big boar hogs are fun with A-Frames, never used solids on them though.

I have no clue, but probably this abomination

I had a buddy that had a .240 Rhyne. I recall it being a 7mmMag case necked to 24 caliber. It went somewhere in the neighborhood of 3500 - 4000 fps.?
Only thing 100 rounds later that barrel was toast.

This was pretty interesting, it might be fun to slam a 1-8" twist 27" inch barrel on and play around with both, the .25-06 and the .257 Wby Mag using those 130gr plus bullets, of course, I see the .257 Wby Mag giving the best showing overall due to case. But, if this guys facts and findings are good, well, why not?
Cheers.

120 gr speer BTHP? pretty good BC

Lol, Nearly all of north dakota, south dakota, eastern montana and Wyoming, Nebraska, Kansas, Oklahoma, Texas...

Realistically, in Texas, Oklahoma, and New Mexico, you can rarely see over 200 or at most 300 yds. for hills, brush, timber, and the occasional mountain. Montana and Wyoming have their own terrain that limits sighting distance, but we won't get into that. Obviously, I am writing about hunting country terrain, not the view down the Interstate Highway.

I though smokless powder gas move at 5000 fps. If so that is the speed limit

120mm with depleted uranium sabot with muzzle velocity right at 5000 fps?

Sure would like to see you put one in your pocket ? lol

These are truly amazing rounds, check out the statistics below and the statement at the end.

The muzzle velocity of a 120 mm APFSDS can vary depending on the model:

• 120mm APFSDS: Has a muzzle velocity of 1,790 m/s at +21°C
• 120mm Tank Gun KE Ammunition (APFSDS-T): Has a muzzle velocity of 1,740 m/s
• 120 mm APFSDS-T: Has an initial velocity of 1,670 m/s

In general, APFSDS (armour-piercing fin-stabilized discarding sabot) rounds can have muzzle velocities ranging from 1,400 to 1,800 m/s (4,593 to 5,906 ft/s). Modern APFSDS rounds can also be "ballistically flat" for up to 1,600 m, meaning that gravity doesn't significantly affect their trajectory until that distance.

55B school Redstone Arsenal 1986. Pretty sure I'd need big pockets if I remember correctly

They sure make a 63 ton tank rock.

That's strange where I hunt I can see 1200 yards west, 800 yards east 650 yards south but only 100 yards north
My wife has a 650 yard range from her stand.

The flat hold hair champ I have is one of my 257 wby with 85 grain bullet---hold hair to 400 with out much thought just shade high or a bit low.

The overall flat out to what ever distance is my 30-378. But man it barks

 

[victor3ranger]

I haven't loaded any 120's in my 7STW but I bet that the 0-400 is pretty freaking flat.
I know that with my 140's at 3535fps is going to be pretty flat
