My fall moose hunt raised a few questions about "knockdown power". It started with my moose kill. 150 yds., 340 wby mag., 225grn swift a-frame loaded around 3000 fps. 45" legal(4 brow tines)bull shot right through the middle of the heart. Upon impact, the moose runs about 60 yds. then stops, turns to see what the heck hit him. Another 10 seconds goes by before he starts swaying back and forth. Finaly, like clockwork, drops dead. Fairly ordinary.
Three days later, my wife shoots a 59" bull at 200+ yds with a 338 federal, the bullet (a-frame) is traveling around 2300 fps at impact and the bull drops like a rock from lung shot. I thought that was somewhat spectacular but I didn't think too much about it untill one day when my son and I were out shooting cans. I'm was using a 22 and the bullet goes right through the can, wobbling it a bit each time. He's using a bb gun and the can goes tumbling off the rock. Now I'm thinking, thats interesting.
So, other than the luxury of a few inches in trajectory, do you think more "feet per second" is always better? Can there be a majic velocity between 2000 and 2300 fps that knock game sideways? Was my coffee to strong?
