  Matrix Ballistics is a Canadian based bullet maker focused on making high quality hunting and target shooting bullets.  

  This particular bullet represents an outlier in terms of weight for the 7mm caliber.  Normally, 180 grains is the heaviest weight that most bullet makers will attempt for 7mm, so this 190 grain has a high BC and truly stands out.

   Made on the extremely precise J4 jackets, these bullets are proving to be a very accurate and high performance option, which is great news for Canadians who often struggle with supply issues of US made bullets.
