I have a 28 in. 5R heavy varmint contour barrel on my 300 RUM. I'm thinking if I wanted to fry my barrel I could get 4000 fps with a 110 to 125 gr. Bullet but something about a 215 gr. Berger Hybrid at 3140 fps. Works for me on elk , deer and lope. I'm not against hyper fps at all. You have me thinking now about a125 gr. at 4000 fps for lope beyond 500 yds. Interesting.

I don't think there is any appreciable difference in barrel life, though haven't tried it.

Certainly can't see any fault in your current load.

So just for discussion I understand it the opposite of what I'm. hearing from you?

I see the bulk of the advantage for the 124 class bullets inside the 500 yard mark, with heavier taking over past that.

We also have other cartridges pushing light for caliber bullets notably gltaylor being over 4000 with a 6.5 caliber 85 grain.

Having seen a couple of animals taken with hypervelocity impacts isolating for high speed impact regardless of caliber remains of interest.

I totally agree that heavies will take over at longer distance .

6.5CM “ultimate LR cartridge” ??
WT-Frick? I dig the 6.5CM, and It’s a defienlty a lot better than the 308, but “ultimate” anything it is not.

Readily available quality factory ammunition, high BC bullets, low recoil, inherently accurate, better Sectional density, and Better ballistics than the .308 all make it a logical choice over the 308, especially when speaking in regards to the .308 vs 6.5CM for use in the .Mil precision weapons systems

Only con as I see it is the barrel life
Alot better than a 308 by whose standards sounds like you've got a grudge against that pretty reliable and extremely widely used cartridge

Lol. Easy there. It’s not about grudges. It’s about the numbers. Just because a caliber has been around for for a long time and you like it doesn’t make it “better” than XXX caliber. It’s just means it’s older and you like it 😉

308’s hold a special place in my heart. Was my primary weapons system for quite a few year and caliber of choice for a time after that, but facts are facts and the numbers don’t lie. feelings aside. the 6.5CM is ballistically superior to the 308 in both trajectory, drift and energy on target at distance Recoil is less. As I said, the only con to the 6.5CM I see when compared to the 308 is barrel life. Hornady ammo shoots lights out, and is readily available. The 308 will
Bit slightly harder at close to medium distances but the CM retains its velocity better so it’s gonna hit harder at the extended ranges.

Just because the 6.5CM is superior to 308, Doeant mean the 308 isn’t good or that I have a grudge against it. Its iconic and a classic . Performance wise, It’s just not at same level as the 6.5CM.

Ron's choices in the video are not impressing me. He is showing common cartridges that don't do too badly but IMO there are quite a few that are much flatter. The title says "flattest shooting cartridge ever", I disagree.


I remember many years ago John Lazzaroni made a special 308 warbird with 130 gr bullet. IIRC it was good to 500 yds without touching the turret or using stadia. He currently offers a 150 gr nickel/teflon plated X bullet @ 3819 fps

I have a few loads that are flat shooting:
300 Rum with a 168 Berger velocity 3560 fps
257 Weatherby and 115 Berger 3685 fps
6-284 and 55 gr nosler BT 4200 fps

Looking at Nosler's load data I found a few more

300 RUM and 125 nosler bt or accubond @ 3900 fps
7 Rum and 120 Nosler bt @ 3700 fps
26 Nosler and 100 gr ballistic tip 3960 fps
27 Nosler and 130 gr ballistic tip 3600 fps

I realize some of the aforementioned loads will have some wind drift at longer distances but Ron's video was titled FLAT SHOOTING CARTRIDGE.......


Bet there are some rifles that you guys shoot that blow these away.
It did say"flattest" for sure! Too save a barrel by going gas volume over gas pressure can get those puppies out of those 30+" barrels.

It's only better on paper and that's it cut and dry, It's no better than trigger man is

And this thread is about flat shooting cartridges and the Needmoore didn't make the cut so stay on topic please,

Yea, what’s on paper? that’s called “science”. AKA undeniable facts. Sorry but all cartridges are not created equal. The Rifle, Shooter, ammo and optic are all part of the equation. don’t care how good a shooter you are, your 223 ain’t gonna cut it at a mile. Your equipment and its limitations matter, unless of course you never shoot past 4-500 yds and if that the case then none of it matters. Hold High and sling it as fast as you can.

And what I posted was in response to
Someone quoting me back from Page 1. So the topic is what it is.

Once again the topic is Flattest Shooting Cartridge's

I mean no offense but If you will take notice it took 7 pages for someone to finally quote your response on page one, Why you may ask? Because 99% of us disregarded your post as it had nothing to do with this discussion whatsoever so instead of turning it in to a dumpster fire on page one we made it 7 pages before the chest beating Needmoor crowd showed back up, Is the Needmoor a great round ? It Absolutely is but I don't care for it so when I see a new thread that says Needmoor I do not participate as I have nothing constructive to add to the thread, Once I mean no offense but it's reply's like yours ( and many others) that turn really great discussions into trash piles, I would also like to commend you on your very adult reply of "Neato" .............. Bravo Neighbor ................... Bravo
