I too have a Knight Vision and love it. The BH209 does do a great job and is very accurate. My most accurate load was shooting 100 grs under a Hornaday FPB bullet. I know this bullet is very heavy at 350 grs for a deer sized animal, but it is very accurate.

I had three bullets all touching at 50 yds with a point of impact at 2" high. I went over to the 100 yd range and got a nice three shot group inside an inch and a half with a POI at 1" high. I really love the idea of only loosing an inch between 50 and 100 yds. I only wish I could shoot my gun out to 200 and 300 yds to further the test of this powder.

At first I was very against this powder due to the price. I think it is highway robbery, but for what it does I guess I can afford the extra cash for now.
