"...Basically, he was dead after the first 2 shots, but I kept the 300rum barking until he stopped moving !"
You did it just right sir!
Congratulations!

I personally have near zero interest in proactively shooting a brown/griz - but if you're going to do it, that's the way! And darned good shooting!
Congratulations on a fine bear and a great experience. Looking forward to the mount pics.
Well done!
