The 90 gr GameChanger is a very hard bullet and is meant for more velocity than the 6 x 45 can must with it...

it was designed with heavy game in mind, using max velocity out of a 6mm Rem or a 240 Weatherby or 6/06, or some other eqivalent.

I learned that after the fact, given bad information from one of Sierra's techs before using.

ONe of the ballistic tips or the Speer 105 SP or the 100 grainers is more in line with what I was thinking.

Shot the 223 today and beside the 6 x 45, it was an eye opener side by side.

The 6mm version is a big step up over the 223, even with heavier bullets.. especially in bolt actions.
