Interesting observations Velo Dog. I wonder if the velocity of the two rifles had something to do with it as well. I suspect that these super fast rigs really challenge terminal performance.
My go to bullet for deer in the 7x57 is the 160 gr Speer Hot Cor. It’s a bang flop load. If I do my part they don’t take one step after the shot. Admittedly shots on my farm are not long. I think the longest I’ve taken has been 250, but 100 to 200 is typical.
That might have something to do with it, I’m not sure.
It is possible.
However, the .30-06 when loaded with blunt shaped bullets appears to me, to be more effective than it is with spitzer bullets.
Also and in all fairness, sometimes the super velocity cartridges do produce some spectacular drop-to-the-shot results, on deer size animals.
From what I have seen, this however is virtually always at normal hunting ranges, not out around 4 or 500 meters.
Also, such spectacular drop to the shot results are more often than not, accompanied with a lot of unnecessary bloodshot meat damage and a huge exit wound.
Having said all that, I do like the .300 H&H Magnum, 180 grain spitzer, as well as the 7MM Remington Magnum 150, 160 or 175 gr., for the specialized niche they were designed.
In other words for longer shots, in more open geography, sparse foliage.
My capability from field positions to consistently hit the vitals on most of the types of animals I’ve hunted is about 400 meters.
For this, the above 2 calibers mentioned are quite excellent.
That said, the hunting for hooved game that I have done, nearly all of it has been at much shorter range.
Therefore, I don’t bother with the .300 or 7mm Magnums any more.
Cartridges such as the .30-06 and .375, with heavy for caliber round nosed bullets, shoot plenty flat enough for what I require of them.
I am envious that you have a farm whereupon there is good deer hunting.
I live in the woods but within the city limits.
Animals, including moose, bear and Lynx visit us here each year.
However, hunting is unlawful in the city (except falconry for fowl and bunny).
But I’m too lazy to take up falconry. LoL
