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

Is a 6.5 Weatherby flatter shooting than a 338 Edge, or 300 RUM at 1000 yards? 2000 yards?

I have a 338 Edge and a 300 RUM but I don't load them for that kind of game.

The 6.5-300 is flatter at 1000 than the 300 RUM and a 338-378 throwing bullets intended to be "flat". Let me run them to 2000 and then edit this.

Yeah the 6.5-300 is flatter to 2000 I provided a link to Ron Spomer's data in this thread. It just takes running in the calculator to get the 2000 yard number.
inches ToF
6.5-300 -846.8 2.429
300 RUM -890.6 2.491
338-378 -1005.1 2.505

Does the 6.5-300 wby have enough killing power at 1,000 yards for moose and elk?

Not my job man. Above my pay grade.

The really big calibers will be flatter for long range target shooting, say past 1.5 miles. That's because 375 and 416 caliber bullets can easily exceed the best 6.5 bullets. Bullet length is limited to about 6-7x the caliper. 6x caliper is 1.58 inches for 264 caliper. For 416 it's 2.5 inches. A longer bullet can be designed for higher BC.

Warner Tool has a line of copper long range target bullets designed for highest BC. Their highest G7 BC for calibers 264, 284, 308, 338, 375, and 416 are 0.32, 0.36, 0.42, 0.48, 0.55 and 0.64. At very long range a 264 bullet has no chance against the big calibers if muzzle velocities are even close.

Well, one of my 30 caliber 52 grain 22 caliber sabot loads at 5,000 fps is very flat.
When zeroed at 300 yards, it is only 1.45" high at 200 yards, 10" low at 486 yards, 22" low at 600 yards and 122" low at 1,000 yards. Data based on my elevation of 7,500 feet.

If your favorite isn't chosen as the "flattest", move the goal post. Been going on for decades.

Also, flattest to what distance?

Are we doing categories?

500, 1000, 1500, 2000 yards?

Flattest shooting in my mind means...

You are not using the elevation dial....

You are not using some Christmas tree reticle to do hold overs...

Flattest to let's say 500yds. Point,click, get the skinning knife type shooting.

That is a valid "flattest" parameter. If I understand you, it's longest "Point Blank Range".

What "kill zone" size are you thinking?

6" at the largest.

I'm not interested in "clicks to a mile" for this application.

My 25-06 has a MPBR of 297yds with a Barnes 80gr ttsx......on a 4" target.

on a 4" target.

It's a thing for the database but I'm more for 4" diameter/2" radius.
