130gr .270 factory load pushes 3050 from a 22” barrel
At 220m it’s dropped to around 2500-2600
That’s more than enough to expand especially with the size of hollow point Fox bullets have.
We tested Fox and many others into gel and clay down to 2000fps.
They still expand at 2000
If you shoot a bullet that is designed specifically to hold its original mass and not fragment (to produce cleaner carcases) through the lungs without hitting a major vessel, you are more likely to get pass through, smaller exits and if shot high lung, slower blood loss through that exit.
Lung material carries a very low pressure blood supply (it wouldn’t work as a gas exchanger if it wasn’t low pressure!)
Between skin and skin on a pure lung shot you have no major vessels.
Your textbook DSC1 target is a lung shot, not a heart shot
This lack of observed blood trail is almost exclusively shot placement.
You could shoot them directly in the low heart with a steel ball bearing and get a massive Blood loss through the small hole!
If you are observing the shot placement on the recovered Carcase you have by default added one more to the list of successfully killed deer….regardless if it didn’t leave a snail trail of vital juice.
For every example of no blood trail I and many others could and have shown first hand examples of the complete opposite.
I shot a roe at 225m last week or so.
Pulled it slightly forward and took it forward of the front legs behind the sternum, severing a major vessel.
Small entry
Small exit
Deer slid down hill with a few kicks of the back legs
Through the thermal the blood trail was 2ft wide and 10ft long!
You could argue that having to alter shot placement with copper is demonstrating a design flaw
You could also argue that the use of an SST or a fragmenting bullet of lead or non lead construction on a high double shoulder shot and the subsequent destruction of the entire front end is also a design flaw…..
The perforation of the diaphragm by fragments on a text book broadside engine room shot..
The destruction of loin through large fragments taking a non linear exit…
The vacuum effect of sucking green through the diaphragm without direct perforation….
Non linear pass through (bullets turning)..
All design flaws of standard cup and core or fragmenting non lead bullets that have been reported numerous times.
You don’t need to destroy any Carcase with a fragmenting bullet to get a good result, with any bullet material.
Increase your sample size and evaluate what you have hit internally on every shot before you conclude that it is the material, the brand, the velocity, the calibre, the rifle etc etc
Forestry England evaluated a sample size of 500 rounds of Fox 130gr .308 (same weight, same velocity, bigger calibre) before committing to the brand 5 years ago
I would argue when 85% of those (one brand, done for every brand they use) are documented field results that THEY have the biggest studies of non lead, not any YouTube advertising channel.
They simply don’t use any products that don’t work as has been shown by them dumping certain calibres, optics, moderators and ammo from the list of authorised products…..
Plus we have stock….
Not always the case with US products
yep its a dead deer!
