I thought I would share this with you.
Two weeks ago I shot some typical NZ feral goats,a nanny for eating and a billy cause they smell
,they were not large but big enough, both at 661 yrds with my 338 LM, 300SMK with a MV of 2830.
Both were hit through the shoulder, the nanny was a boom flop, the billy was a boom..impact.. rock from side to side.. blood trickle came out... FLOP,stone cold.
I dressed out the billy for pet food, nothing too special small hole one side 1.5" hole on the other, heart and lungs mush, expected damage.
Turning the thing into mince for the pets there was nothing found of the bullet jacket, core not a trace.nothing
The nanny was much the same in field dressing,two holes one big, one small
heart, lungs mush.
A couple of days later after hanging, it was cut into peices for a curry, and in the middle of the right back strap was piece of the jacket about 1.25" long and 1/8" wide, in the whole animal thats all that was found,the rest of the bullet went through.
So this answered a question for me too,a 300 SMK is relativly frangable even at extended distances, on game.
This surprised me considering the physical size of the bullet compared to the game I thought it would just pencil through the animal, Oh no they dont.
I think its a good thing knowing that they can expand and even if the jacket does tear its self apart,a lead core with that much energy in it is going kill most things, IMO.
Just my 2c, I hope one day to get over there to get me one of those cool looking critters.
