Love this post. It not very complicated. I think the exact thing stinky coyote wants (a predictably calculator of sorts) is partially how the whole “pretty bullet “ phenomenon took hold. Here is the level of mushrooming at x different velocities. Super predictable right?
I’d rather have a less predictable or at least harder to compute mini grenade going off inside the vitals than a “more predictable” trajectory of a mushrooming bullet.
the light really went on for me when form talked about how with big magnums especially, the desire for mushrooming, strait penetrating bullets was so paramount companies had to keep increasing jacket thickness or go to a mono. Because fragmentation was seen as bad thing. It’s all about looks. Keep increasing hardness and remove fragmentation what you get is a literal strait line through the animal like an arrow.
Would you rather stabbed with a spear strait through you or have someone stab you with a knife then put a small grenade in your body? Which one do you think would be more easily repaired by a team of surgeons?
yup, but all subjective for most part, it's what we do
bell figured out with a little over .3 sd solids impacting 2200-2300 fps will get through a 1' foot of elephant head to get to the off switch, and with fack all for energy as compared to the .700 nitro where 5x the energy wasn't making it deep enough because it was lower in both sd and impact velocity, so it's not hard to see you need an unchanging sd of .3 or higher and impacting at 2200 or above to make anything work on big dg
or to drive the subjective picture home you could run into the elephant with 10x the energy again with a Land Rover at 40 mph and end up a grease smear yourself as the elephant shows you it's disdain...or run a spear through, sledge hammer vs spear, same impact velocity, same weight, entirely different sd, at some point the penetration has to be there, it's only one part of the equation, once there then what work is available for damage along the way is the other thing?, not much is needed but more does mean faster kill, less work better hope it's a sharp spear so at least it will bleed (broad heads on arrows) to speed up the process, but if you wanted to get as deep as the solids yet still throw a grenade on game that size your shoulder would vaporize under the recoil it would require...so penetration trumps always, you HAVE to make that bullet keep it's sd in order to get it deep enough on those animals and all available energy goes to the penetration, not much left for grenade work
our game is bunny rabbit tender in comparison, so we can utilize grenades and still keep our shoulders while getting as deep as we need
but wouldn't it be nice to see all of that explained like a dyno curve for a motor?
numbers instead of sledge hammer vs spear subjective visualizations? you know...the same thing we've been doing all this time?
imagine, we would see by numbers why the old partition is basically similar performance as new eld-m, old partition grenades the front, hangs onto the tail, but starts with lower sd (say .2 sd) so had to hang onto tail to make penetration depths, the new eld-m just add more bullet length which increases sd (say .25 to .3 sd) to compensate for lack of a partition wall...people will laugh at that comparison but if we build a dyno for this...you will see how close I am to right (objectively, by numbers)
