I have just returned from an exceptionally successful hunting trip and wish to sing the praises of Sierra's 85gr hollow point gameking in .243! Wow - what a bullet! I shot 14 animals up 80 kg in weight and if they were not dumped on the spot it was my bad shot placement - most did fall immediately. If anyone is considering using these little 6mm bullets DO NOT HESITATE!!! They are potent and above all their accuracy is astounding. 5 of the animals were shot beyond 250m and there was still plenty energy - in two cases I shot right through the animal. This is beyond doubt the best bullet I have used - 2 head shots were taken at 300m with pin point accuracy. Well done Sierra - I am impressed! I have been using these bullets for about a year now and finally fine tuned the load. I am a happy man. I wonder what the limit of it's performance is regarding animal size and distance. From what I experienced I am sure it will drop vewrey large animals fast - comments please?
