Sneak, the bow is marked 63# at 28, but I yank it back a little further most of the time. The arrows are 30.5 inches.
I never have heard the whistle, but after working around airplanes most of my life my high pitch hearing is pretty much gone. If an elk is quite a ways off and is bugling, I won't hear it. That's what my kids tell me.
More about the broadhead. They really get sharp when you work on them a little with a diamond sharpener. I know they are supposed to have a pyramid tip, but if you're over 45 you WILL need reading glasses to see it. I ended up putting more of a pyramid tip on them just like the original ones. The tips on the new ones don't bend like the old ones, but they do chip off a little, hence the added trimming I did.
I decided to see what happened on a shoulder blade shot. The arrow actually went in about half way, into the lungs, and I had a dickens of a time getting it back out. Of course, that's shooting a 700 grain arrow at probably 70 lbs. pull from five yards, and I'm not sure where on the shoulder blade it hit. It did bend the steel insert in the broadhead some, and one of the blades was a little depressed at the aft vent area. I'll send it back for an exchange. The upper hole is the bone shot.
And no, I didn't get to try them on any of these.
