If it's a flyer (see what I did there?) it might increase the ammo output to cope with it.
What I don't like is the testing at 50yds for a so-called 200yd cartridge.
I'm not sure who has suggested HMR is a 200yard cart, it certainly has the energy to stop any small vermin, even fox at that distance BUT.......
.....even though I have used it many a time at the range at 200, and admittedly a handful of times in the field at that distance, I personally, and definitely, do not see it as a go for, daily, 200 yard cartridge.
