JamesB,
I have used the 90 HPBT Gameking exclusively in my 25-06. The rifle is a Browning Composite Stlaker. IT loves the Gameking. With regards to deer, it has taken at least three a year for the last 5 years and none have gone more than 15-20yds, most fell where they stood. I wouldn't change at this point if I were given free cartridges.
