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

[DUCKMAN11]

220 Swift

Dad has one and it's a hammer! I've not seen a finer combo for headshots on cull deer out to 200yds! But if i lost a peice of brass I'd probably get cut out of the will.....and I'm an only child lol

 

[DUCKMAN11]

6PRC/SI, 25PRC/SI, 6Max, 25Max, 257Wby, 264WM, 26Nos

6SS, 25SS, 25sherman, 6.5mega, 300mega with a 110vmax....... me and Phil have pulled this all apart lol. 22SST could be fun if it wasn't a complete disaster and you could get N570 or RL33 nuggets to fall into a .224" neck lol

So you need to qualify your question with a few more requirements. Flattest shooting means nothing unless you add a range requirement. Many examples given are extremely flat shooting to say 300 yards and then fall on their face. Such as the 17 rem, 204 etc….. out to 250 -300 yards certainly flat shooting, at +500 yards all but worthless.

You also need to include info like if your want to have a pelt friendly rifle or just want to kill the yote…. Those two criteria will greatly effect the choice of cartridge. I offer many wildcats in my custom rifles that are ultra flat shooting to 500 yards. My 25 and 26 Stalkers loaded with a 100 gr bullet at 4050-4100 fps are about as laser flat as they come to those ranges.

Someone wants to extend their range to 1/2 mile, my 27 Stalker or 7mm Allen Magnum are about the tops with proper bullet selection. If you want legit Long Range, over 1k yards, there are better options there. Need to add in a few qualifiers to get back the most useful recommendations to your questions…

Sorry you are right and I should change my original post but im looking for flattest to 400yds and I don't care about fur friendliness....quite honestly id like to blow them to pink mist if possible! I'm also not trying to use a whole pound of powder to load 4 boxes of ammo.

240wby is essentially a belted 30-06 necked down to 6mm correct? I'd like to hold on heads out to 400yds.

Pretty much.

.284 or PRC case will also get you to roughly the same places necked to 6mm. Just more work and custom dies so more $$ and time.

I suppose you could go 280AI necked down to 6MM to get the most capacity out of a 62-65MM case.

Have you actually tested those 163? And do let us know how that 180 turns out!!!! I'm super curious, that seems like it might be way past the point of diminishing returns regarding weight vs bc vs velocity but it's so cool that someone actually tried this and made a bullet like that! Kinda reminds me of the "Wildcat Bullets" from when Kirby Allen was entering the scene with APS cartridges, another lesser known oddball Canadian bullet company making extreme heavy for caliber long range bullets (the deceased "matrix ballistics" comes to mind as well, also Canadian weirdly enough…)

Just pressure test, thus far. I hunted successfully with the 175 Matrix VLDs out of my .270 AI. I have 165s, but have not tested them yet.

I wish I always had time to dial.

Most of the time the game never knew I was there from 200 to 1000Y.

22-284 It runs 60 grain pills well north of 4000 fps.

While the track record for accuracy in small arms is abysmal if we're just talking pure muzzle velocity and greatest hypothetical mpbr the ultimate will be a saboted round of some kind. If only they shot worth a hoot.

There's a fella on YouTube used some of the accelerator type sabots in a handloaded .300 win mag to drive .224 cal bullets north of 5100 feet per second.

You are correct about sabots. I would like to see someone put them into a 338, 378, or any larger caliber. They should see 5280 in the rear view mirror.

Our coyotes don't sit still. And I might be able to see 20 miles in any direction but the ground is far from flat. It's pretty easy for a dog to slip in and out of a draw in less than a second or two. Gray coyotes blend into gray broom weed and gray mesquite branches pretty well also. Shots over 500yds are rare due to the density of waist high cover. Our mature coyotes will rarely enter open fields in the daytime and if they do they are in 4th gear or higher. "Hold on hair" is a necessity.

Here's another 25 option also that looks pretty good:

.25-7PRC – West Texas Ordnance, Inc. | Custom Rifles & Accessories

westtexordnance.com

I'm looking at that one also. Pretty close to 257wby and without the belt

I am a heavy bullet for caliber/chambering fan. I do not have a dedicated coyote gun (yet), but I have plenty of deer/antelope hunts that have turned into one. The farthest I have a coyote thus far is 525Y with 175 Matrix VLD at 2996 FPS out of mine .270 AI. MPBR is 261Y at 100Y sight-in per calc in #12.

I also have .25 cal (.257 WBY) with 1:7", but I currently load them with 145 Black Hole and 163 Chinchaga. I have 117s from two bullet makers if I want to go light, but I have since put it on the back burner, especially with the 180 Chinchaga coming soon. @Bghunter338

Good luck with your future build and coyote hunts.

Very impressive ballistics! How long is your barrel? If you don't mind me asking which powder are you using with the 175's? Thanks

30" Lilja 1:8" 3G. I have loaded near 3100 FPS with H4831 SC, but group opened up and with pressure. Others are claiming ~100 FPS, but never tried it.

.257 Wby. Mag. Wife shoots 120 gr Nosler Part at 3300 fps adjusted to +1.7" at 100 yds. You can still put the standard crosshairs high on the critter at 400 yds.
