I agree with this statement but the thing about gel is that it offers a consistent medium so all bullets will be subjected to the same impact stresses.
Shooting at game will never be exactly consistent. One might hit a bigger bone at a different angle at a different velocity and thus see different results with the same bullet. There's no clear right answer to this debate.
it does amaze me that some don't understand this or the benefit of it, we have over a century of knowns, proven winners, a subjective understanding....so if you standardize (gel) etc. and compare all of them we can then see what else will also be a winner and why others won't be, comparing 'on game' is just adding more subjective noise and we have over a century of that anyway
as for stories, I know a 123 gr 6.5 eld-m impacting a sharp quartering away buck at 2100 fps can take the last rib on way in and leave 81% of bullet in the last bit of meat at the front of the brisket after 18" of penetration...when you match construction, appropriate for game sd, and impact velocities for that construction you get wonderful results, don't overdrive the squishy bullets and it's a wonderful thing, I also know that same bullet impacting in the 23-2400 fps range will be more like 50-60% retained, although most of the time on broadside stuff we don't get a chance to find out as it exits and also know that at 1700 fps impact it is a perfect mushroom appearing to weigh about 95% of what it started from someone else's example....so you have to be able to visualize things out for certain bullets as it's a range, the depth of penetration will vary a few inches but still adequate in close but actually goes deeper and maintains it the further you go out as it retains more of it's sd
so my subjective example says the specific .25 sd eldm example here will range between 50-95% retention from 2400-1700 fps and subjective guess on all I've seen will be 18-24" penetration range, if you wanna run a bullet like that hotter and maintain those penetrations you'll want to start with more sd...basic logic, or use tougher bullets, the range of performance and options and we didn't touch on the subjective point of what happens when you dump a bunch of bullet upset inside the animal like that? more drt's and short recoveries vs delayed controlled expansion bullets that dump as much or more of their 'work' in the hillside after passing on through, we all come to prefer something on this journey, it is a dynamic range of performance but we'd come to find so many options we use overlap but...
wouldn't it be slick if we had calculators and the right numbers to look at of all bullets compared to each other to see this objectively and save about 30 pages off all these threads and make choosing so much quicker and easier?
