Don't think so. What kinda proof you got.

Let me specify. 140s in the 6.5 and 180s in the 300. 6.5 at 1000 has 800ft/lbs of energy and the 300 has 915ft/lbs. if you jump up to the 210 then the spread widens to 800 and 1150. My 300 doesn't like the heavies.

Where are you getting this information?

You can calculate it with just about any ballistics software if you know the BC, weight and velocity. I have an excel file where all I do is plug in the data and it spits out the information. That being said you can go to a Bergers website and do the same.

What are you questioning?

Is the 6.5/286 comparable to the 6.5/300 wby?

Not really you are 3400 with the WBY out of a 26 and I'm like 3100 with the 6.5-284 long action from the same length barrel.

Basically the 6.5-284 in a long action is a significant improvement from the 6.5 Creed or 260 if you are shooting a target rifle in my opinion. Not like that is going to be a light rifle in either case.

Ok I gotcha. I want the 6.5/300 wby in a mark v. Just done have 2-2.5k to drop on one YET

I use the app shooter. Hasn't let me down so far.

As for the data on my 300, with my hand loads, that are mild,i am running 1111 ft/lbs at 1k yards.

And for the record I use known data (velocity). All my loads are ran through a chronograph while testing.

I'm not as advanced as some of you. I have a friend with a chrono, so I know my velocities, but I just ran my numbers through the berger webpage ball calc. It was almost spot on all the way out to 1000.

I have a 6.5X55 swede sporter. I think if I go custom in the future, I want to do it off that caliber. My sporter is a tack driver, and a 120+ year old 6.5 mm cartridge is almost too good not to try.

I still like my 308 though. It's a $550 used rifle that was shooting right there with the ruger precision the guy was shooting beside me in 6.5 CM, with a scope that was double the price of mine. Also, brass is everywhere, not loading up a keg of powder for every round... yeah a grand is effectively maxing it out, but right now, that's all I need. BABY STEPS!

That's right man baby steps. The 308 is what I started out with and have progressed to bigger and better. I didn't have anyone to teach me I have learned everything on my own.

According to my loads with a 300 mag going by bullet drop app with 180 gr leaving the barrel at 3080fps chronographed, energy is around 1000 ft lbs at 1000, best I see a 6.5-284 is around 700 ft lbs with a 140, that's all I was saying. I have know idea if any of the info you or me is providing is right or wrong.

Which bullet and what speed for the 6.5. I'm pushing the elite hunter 140g at 3k and it has a BC of .606. Energy is in the mid 800s at a 1000.

I'm sorry for hijacking the thread here but what does energy matter in this case. It's only relative if your killing something.

Short answer is you are absolutely correct and I've derailed this thread pretty bad. Sorry OP!!

It's still valid though. The higher the energy means the higher the BC. BC and energy dictates how fast the bullet drops and how well it bucks the wind. Most of the long range target bullets hit with more energy than hunting bullets. They just don't expand as well.

BC honestly is all kind of relative. The BC's published on every box of bullets are listed at a specific velocity. If you do not obtain that velocity the BC of the bullet will not be as high. Like I have said above everything I know about long range shooting has been self taught and you may know a hell of a lot more than myself but I don't see how much energy the projectile hits with (force) has at any impact on the projectiles BC during its flight.
Target bullets have a different jacket that makes them not proper for hunting, i.e. They won't expand.

Energy is a product of velocity, weight and ballistic coefficient. When talking about long range shooting all three are important to a degree. That was the point I was making.

I don't think it makes all that much difference as long as you are shooting paper.

I learned with a Mod 70 in 30-06 with a 10x external adjustment Unertl. One of those scopes that looks like a pencil and is about as long as the gun barrel.

You can get a different rifle and go shoot 1500 yards or even further is you want. If you know the distance sitting on the range and you've already got your dope figured out all that... big deal. You'll hit it.

If you want to challenge yourself shoot unknown distances. I know plenty of people who can shoot 1k, I know far far fewer that can just plop down somewhere range a target and shoot it and I know about a handful that can do it without some type of ballistic computer aide.

Impressive. Which Vortex have you got?
