One of the few brands tested down to lower velocities.
We tested them in ballistic clay and NATO strength (20%) gel down to 2200fps terminal velocity
In personally believe from my own experience that they have produced faster and more emphatic killing at lower velocities
I initially started using them myself in 130gr .270 form pushing 3050fps
For the past 18m I have been using them in 150gr .308 form at 2650fps from a 20” barrel.
One of the most impressive results was on a very big stag at around 220m.
Quartering towards me
Shot just in front of one leg, exit just behind the other, above the heart but through aorta and pulmonary vessels and lungs.
Not only did it stop it in it’s tracks within 15-20yds, it produced impressive “shattering” of lungs and huge blood loss through entry/exit and notably the nose and mouth where there was a 1m puddle
