Nope, just one example. Look up any 6.5 and 7mm bullet of the same weight and shape and the 6.5 will have a much better BC, every single time.
I did. 127 Lrx = 139 lrx. Both are .47.

Other common hunting bullets between 6.5 and 7mm aren't that far apart and when you add the velocity that a 7 bore will achieve vs. a 6.5 bore, they just about cancel out. Hence the question.

Why is it you think we need to convince you? Use what you want. Nobody cares.
Where did you read that I needed convincing?

It's a question Karen. Why do you think you need to respond?

I think you might have critical thinking skills confused with the knowledge of specific, unique information. I don’t care about factory ammo or any amount of recoil below 20 ft lbs so I guess as you sa, it doesn’t matter to me.

That wasn’t directed towards you- though you are stating that you don’t understand what the 6.5 does “better”- just the general “I don’t understand or like the 6.5” crowd is that it doesn’t do anything that a 260/7mm-08 doesn’t (which has been stated in this thread), and that is not true. If someone doesn’t care about factory ammo and doesn’t mind a bit more recoil, and doesn’t mind a bit more finicky reloading/setup for precision, the 6.5cm doesn’t do anything better.

The velocity does not cancel out wind drift. At 300 yards it doesn’t make a lot of difference, at the farther edge it does.

? Maybe because you started a thread titled: “Struggling to see the point of 6.5’s”, and ended that post with “what am I missing”. People are laying out exactly what you are missing, but when they do so you start deflecting.

I took my bear this year with a borrowed 6.5 wby-rpm (long story but my buddy shot a bear the day before, and his rifle was 4lbs lighter than mine, so I wasn't going to turn down carrying in 4 lbs less back up the hill) and I must say, I was impressed, he went about 30 feet and tipped right over. I liked the lack of recoil, and it was nice and light. Shot someone else's 6.5cm at the range a few weeks later, and it was pleasant and easy to shoot accurately. Probably won't replace my 300wm or my .270 any time soon, but I may build one for my daughters to shoot eventually. Like the idea of cheap, readily available ammo for them to learn with.

For me, the point was that the best killing bullets, eldm and tmk, in the heavy for caliber options, have been way more available over the past years than the best killing bullets in the other calibers I used to rely on. Factory ammo and fast twist factory rifles are another perk.

You're again confused. Explaining isn't the same as convincing. Nowhere did I say I needed convincing.

Don't make this about me. Make it about the data. The numbers. You've laid out some good points which I appreciate. Keep going with that. Your rationale should speak for itself without having to resort to getting personal.

That's a big reason I dipped my toes back in the 6.5 game, because I've seen a drop in availability of 7mm bullets and lately, brass. So I figured what the heck. I'll give the CM another try.

What I'm hearing so far is that within 500 yards, it really doesn't do anything better than a 7mm-08 unless you're really recoil sensitive. I'm no fan of recoil - don't get me wrong - but it's very hard for me to tell the difference between a 7mm-08 and 6.5 CM. It's pretty insignificant as far as I can tell. But someone who is lighter than 220 lbs. might appreciate the recoil reduction. I don't start to notice recoil until 20+ ft. lbs. (roughly '06 territory).

I don't think that I'm communicating effectively.
Please feel free to explain what you meant.

I get that a 6.5 will have a better BC than a 7mm for a given weight. But I also know that you can't push that 6.5 as fast from the same case.

The loss of BC will be canceled out by increased velocity at normal hunting ranges.

Of course if you're interested in long range, then BC becomes more important.

What your missing is BC
7s are coming around and if there is a high bc bullet you like the construction of and you barrel is fast enough.
Or if you don't shoot far, you're not missing anything.
6.5s have a wide selection of high BC bullets. And tons of GOOD factory ammo.

If the average 7-08 with a cup and core bullet
And a 6.5 cm with a high bc bullet come out at the exact same fps.
At 500 the high bc bullet will have more speed and continue to carry it. The gap just keeps getting worse for the average 7

The higher the bc the more efficient the bullet is at flying thru the air. Think sports car vs pickup .

Also if you are gonna buy an average rifle off the self and hope to find ammo that shoots well a 6.5cm has a large advantage.

I was trying to explain these two facts without being a jerk and it seemed like you didn't understand. I think we're on the same page now.
I just checked the BC's of the 147 ELDM vs. the 162 ELDM. They are .697 vs .670.

That doesn't seem like that much difference to me when, using common load data, they are both traveling about the same speed.

It may but that is not generally the case.
Think a piece of plywood vs a waxed set of skis.

If my be comparable but usually it is not.
You have to compare them in a ballistics calculator.

Of those 2, which is gonna be easier on the shooters shoulder. I used to be in your shoes. A friendly shooting competition opened my eyes to the popularity of the 6.5s, mainly creedmoors
