.223, 6mm, and 6.5 failures on big game

[z987k]

High bc higher velocity more weight all 3 fight wind. If you personally cant shoot bigger gun accurate thats fine shoot smaller but know your distance and capability

Weight has literally nothing to do with wind drift. I have no idea where this ever came from.

The equation for wind drift is this -

Wind drift = Wind velocity * (time of flight - time of flight in a vacuum)

Notice bullet weight is nowhere to be found.
The only thing the person using the gun has any ability to change is the time of flight. Which is made up of muzzle velocity, BC and distance to the target. Assuming distance to the target is the same for comparison's sake. It's just BC and muzzle velocity.

Do you think that 6mm cartridges & bullets cannot have high BC and/or high muzzle velocity?

Physics literally says otherwise

 

[barehandlineman]

what do you think bc is calculated from

Do you think I pulled that forumula out of thin air?

I'm showing you the actual physics. It says you're wrong.

It's not weight.

Do you think a 6mm can have a high bc as a 30 cal? What do you think increases? Oh ya weight & length

Not sure your point. Comparing slugs and fast expanding bullets isn’t much of a comparison, but ok.

Tell me a 338 Lapua shooting 285 eldms at 2900 fps won’t kill better than a 223 shooting 73 eldms at 2900 fps and I’ll just tell you that you’re stupid.

To be fair he is..

He shoots guns with stocks full of trash bags in women’s calibers.

Ballistic coefficient is calculated of sectional density please show me a 6mm that has anything close too 250 30 cal

What is "bigger gun" in your opinion? 300 win mag? 300prc? 300 norma? 338 win mag? 338 lapua? 408 cheytac? 50bmg?

What meets the threshold of "bigger gun" in your professional opinion?

I'm still here wondering what "bigger gun" is...

Actually yeah, compare a 108 eldm to a 150 partition

 

[barehandlineman]

not same bullet guess i should of clarified

 

[mxgsfmdpx]

The last few pages in here are basically saying caliber > skill. Smaller calibers seemingly can't kill anything except some golden calves.



Do you make it to CO? If so, you have access to do the same here. Send a PM.



You're invited too if @mxgsfmdpx makes it out here. Ranges go as far as you can see.

CO isn’t one of the states I frequent or own land in.

108 eldm and 250 a tip both match grade same manufacturer…

Some 6mm bullets have higher BC's than some 30 cal bullets. The highest 30's have higher BC's than the highest 6 because no one makes 6's that long and virtually no barrels have the twist rate to stabilize them if they did.

But to say 6mm's have more wind drift than a 30 cal because of weight is factually incorrect. It's because of time of flight. Yes, SD is one of the variables in BC, but you can make any diameter bullet any SD you want. If you actually had a 6mm bullet with the same SD as a 250gr 30 call, I'd expect the BC due to form factor to be higher.

110 A-tip and 250 A-tip. Read between the lines a little bit.

Everything doesn’t have to be so literal with obscure examples.

Oh, so I should infer and make assumptions??!! Maybe he should have asked a more specific question!!!

 

[barehandlineman]

Why would anyone shoot a low bc bullet long range. Im specifically talking high bc available in each caliber. Highest bc in 30 cal 245 berger 250 a tip. No 6mm can touch that.

 

[Wyo_hntr]

For the elk's sake, what's big enough? 338 lapua? 300wm? Curious minds want to know...I desperately want to be ethical. 50bmg?

 

[barehandlineman]

If you wanna make the comparison then compare same bullet. Partions are bowling balls

 

[barehandlineman]

I wont hunt elk under 30 cal personal choice. Tried it let 22 creed do its thing. Not impressed
