Sectional Density or BC from really Big Game?

I'll pm you tomorrow with a long story about a match that I was at (watching) around 1980 near Lafayette, La. A long, but amazing story. memtb
Back in the day the exceptional shooters used TC Contenders. By the time I cleaned four full legs, 160 shots without a miss, I was pretty much done.
 
Yet that was what was. Today things are different. Stalking so close that you can touch your game has given way to 700 yard shots. I've made 2K shots, I'll buy the drinks for all those that made 700 yard shots that can stalk a squirrel to a tree and touch them! Ann O'Malley's in St Augustine. Hunting is a matter of how close, shooting skills is measured by how far. Long Range Hunting is measured in feet with an MK2. Tools allow for skills, skills drive the tools. If you point your scope at the game and it adjusts via the laser range finder to perfectly correct for the shot, just how much do you suck as a hunter if you miss??????? ROTFLMAO.

Bring on the drinks, I've made over 700 yard shots on game, never tracked or missed, and have a pecan orchard, so stalking a squirrel to a tree, LOL, no problem.
 
Name the time, I named the place. Yet you may have to pet a squirrel on one of my oak trees for a bonafide. LOL. I'll even set you up to a Porter if the squirrel gets away unpetted. LOL.

Bonus for the charcoal with black head, feet and tail.

It's just a grey squirrel with a color problem. Bonus, do they prefer tree nuts or conifer seeds?
Absolutely, I'm bordered by pines on 2 sides and guess where they are? That's one of many fox squirrels I have around, they run out the greys so they get a pass. Squirrels can eat/bury over 30# of pecans a year per squirrel. So squirrels and crows are tied for enemy number 1.
 
Dang it, are y'all in kahoots with my wife? We went from hunting Polar Bears on the ice pack to petting squirrels on the Oak Trees in my yard. What does that have to do with SD vs BC.
 
And as deeply penetrating as possible. Yet since they named that elephant head shots after Bell, I'm willing to concede that he was a better elephant marksman than I will ever be. Nowadays it's not legal to hunt elephant with a 7 X 57, but it's not on my bucket list. You know what the missy stuff between an elephants toes is called? Hunters not as good as Bell or slow natives. 😀
If I remember correctly Bell used to do a lot of wing shooting with rifles as well. Yes.... He was a very very good shot.

He also had either nerves of steel or no nerves at all considering how many elephants he shot at halitosis range.
 
As a 9.3 X 62 fan for Big or Big and Dangerous Game, I've always used projectiles over .3 SD to ensure deep penetration. Yet many people are most interested in Projectile BC. Which do y'all consider more critical for Big or Big and Dangerous Game?
Is there any particular reason why you need to hunt polar bears .
 
SD is only a proxy and really only represents potential. SD = Bullet Weight/Diameter Squared. Bullet design materials, shape, internal construction all play an equal role if not greater role. Impact velocity is also extremely important especially on how it effects deformation with softer nose bullets. There is a trade-off between deformation and penetration (and I am not referring to bullets "blowing up").

Really interesting study done years ago, I want to 1970s about how higher impact velocities resulted in less penetration because the greater and more rapid the expansion created greater frontal area and more resistance plowing through tissue. I think it was Kevin Roberts found the loading his 375 HH down to the low 2300s resulted in a more effective round than at the traditional 2500 fps.
