Thread: Sierras new Game changer bullets

A very specific 1800fps limit on expansion, which no doubt some long range shooters will find out about the hard way.

This is a deep penetrating, tough, heavy game bullet. It will blow straight through most of our game species in NZ. The only applications I might consider using it would be heavy pigs or maybe the largest sambar / red / wapiti stags in the 200-400m range.

I am hoping my cuz in the US will have a detailed report for me after deer season there in the next few weeks as he wants to try them, but has similar reservations.

The GameKing / ProHunter design is ideal for our deer species. They are the same partially fragmenting design, bar the obvious boat tail / flat base. The limitation is their low BC. In the drop tests I’ve done with five common hunting bullets in 6mm, 7mm and .308 the GameKings always came last for accuracy at 400m. But as an effective killer, their track record is right up there obviously.

I think its fair to say that many hunters on this forum would be a bit wary of runners from over penetration and limited or no fragmentation, which has been my experience of using bullets designed for tough game on red skins and fallow.

Good info Flyblown, thanks. I had heard they were a heavily constructed bullet for controlled expansion at higher velocities, hence the 1800fps minimum stated.
