I am shooting 648gr total arrow weight, with the Silver Flame 175gr 1.7/8ths inch cutting diameter. 217 fps on the chronograph. Some would say it's too heavy or too slow, Bulldonkey!
Since I switched to the heavy arrows and big fixed heads you wouldn't believe the difference. There isn't the slightest doubt what will happen when you hit a deer, or whatever. The arrow goes through everything, always a exit hole.
I have watched video after video of the Drury's shooting deer with Rages, yes they get kills with them. But, how many pass throughs do you see? I always see a bunch of the arrow sticking out. Everyone has a favorite head arrow combination, but does your set up allow you to take any shot presented, without worry your going to punch through to the other side.
When I shoot these big logs with big heads they put giant holes going in and coming out, every time. No worrying you're going to hit bone or ribs or whatever. They go through, period! Peace of mind for a quick humane kill.
Oh, btw, 327 grains of arrow is way to light IMHO.
Last thought...KE gets the arrow to the target, just a math problem really. Momentum is what makes it go through. Big difference.
