Ballistic self-gratification. No doubt it was "good" for you.  Holy freaking apples to oranges, batman. Goosey, put your pencil to paper on the 6.5 Creedmoor with 120's and the 257 WBY with 120's. The "spank" turns into a mild scolding when you actually compare apples to apples. Then, just for grins, tack on 10mph to your wind velocity.  Make it a 123 Lapua Scenar in the 6.5 Creedmoor vs any 120 in .257 Roy. That is as fair a comparison as can be made.
What could be a sadder way to end a life than to die having never hunted with great dogs, good friends and your family?

I know I always like to compare cartridges requiring 45 grains of powder... to those requiring 70....
You better pray to the God of Skinny Punks that this wind doesn't pick up......

Yeah that was my thought. Half the powder, and then compare 120s.

In the 80's, IIRC, AAgaard wrote of the X bullet doing the work of a lighter bullet. Granted the BC sucked. The attributes of BC and bullet proximity to the rifling are well known...maybe since the beginning when rifling was introduced. It has been some time anyway...
Generally, yesterday's BC could be offset by powder increases and terminal performance with bullet weight.
.
Today we have both BC attributes and bullet construction performance superior to anything in the past. Downsizing makes more sense than ever.
Not that I want to ruin anyone's fun...just saying

I don't think the 6.5 Manbun is giving up anything. A deer within 300 yards leaves room for a lot of cartridges to shine.

Whoa, you mean to tell me that a 257bee with 70gr of powder pushing a 80gr ttsx is going to shoot flatter out to 300yds than a 6.5 creedmoor with 42gr of powder pushing a 147gr eldm??? Whoda thunk it???
Next your probably going to tell me a 338-378bee has more power than my 22 MAGNUM????
I’d like to see the math that proves that....

So who the hell uses 300 yards as a comparison of these two cartridges? Sounds like something the MSM would do in a politcal poll.... Hell, almost any rifle is suitable to 300 yards....
Use a more realistic comparison distance and bullets and let's see where the chips fall..... I'm thinking both rifles- 120 grain pills- the 6.5 more than holds its own at much longer ranges....

I decided to do a bit of math and found the old 257 can still whoop the Fadmoor! ... I determined for each the odds of killing a deer at 300 yards with the following parameters: ... And the result? ![[Linked Image]](https://i.imgur.com/LNuNuzp.png) Creedmoor was snatched. Doing pretty good for a 70-year-old cartridge. (the results may change if you own a laser rangefinder and are allowed to use it in season)I'd like to see the math that gives the 6.5 Creedmoor/ELD-X only a 57% chance of killing a deer at 300 yards with a 2/5mph wind. Hell, I've gt a better chance than that with my .45-70 and .375 Winchester lever guns and 2200fps flat nose bullets. Put an accurate Creedmoor/ELD-X combo in a competent person's hands and and the probability should be near 100%.

A good .30-06 is a 99% solution.

... I didn't realize just how badly the .257 WBY spanks a 6.5 CM until I checked ammo availability and cost and ran both through the ballistic calculator. From an availability standpoint, Midwayusa lists 14 .257 WBY loads from $39.99 to $88.99, but only loads from $51.99 and up are in stock. The WBY 80g TTSX load goes for $88.99. By contrast, there are 52 loads listed for the 6.5 CM with prices ranging from $12.99 to $59.99. The Hornady 143g ELD-X ammo goes for $35.99. These loads were used for comparison, sticking closely to the OP's original choices (there is no 147g ELD-X): .257 WBY, 80g TTSX @ 3870fps (Weatherby ammo data, 26" barrel) 6.5 CM, 143g ELD-X @ 2800fps (Hornady load data, 24" barrel) Using 7000 feet altitude. 10mph xwind and MPBR zeros for a 6" diameter target, the .257 WBY definitely shoots flatter: At 300 yards: -0.53" for .257 WBY -3.77" for 6.5 CM At 600 yards: -33.2" for .257 WBY -57.5" for 6.5 CM But what about retained velocity and energy? At 300 yards: 2995fps/1593fpe for .257 WBY 2475fps/1945fpe for 6.5 CM At 600 yards: 2270fps/915fpe for .257 WBY 2173fps/1499fpe for 6.5 CM And drift? At 300 yards: 5.7" for .257 WBY 3.6" for 6.5 CM At 600 yards: 25.5" for .257 WBY 15.4" for 6.5 CM Given that drop can be easily and accurately compensated for, I'll take the 6.5 CM/143g ELD-X over the .257 WBY/80g TTSX for ALL my hunting needs. * Higher retained velocity past 700 yards. * Higher retained energy past 80 yards. * Less drift at all ranges. Tell me again which cartridge/load is getting spanked?

Yeah, but how much is the lipsey's exclusive 147 ELD-X? I gotta think it'd make the Weatherby a bargain. LOL It takes 70 grains of powder and light weight bullets to kill deer at 300 yards most effectively.....the proof is in the calculator....and the secret is in the belt

Don't speculate when you don't know, and don't second guess when you do.

It's your Delusion(s),feel free to convince yourself of whatever you need to hear. Obviously,your "life" is wayyyyyyyyyy shy on all facets and your Insecurities grow by the day and rightfully so. Congratulations?!?
Bless your heart for TRYING.
Might I suggest dangling one of my pics,saying something I coined or perhaps punctuate in accordance,if only to further you...from YOU.
It's the ONLY "chance" you've "got".
