Today's bows
 

Man what a world of difference. You new bowhunters have it made - really.
Way back when, when I started bow hunting. Long before the advent of compounds you had to be a gorilla to have enough bow to get both speed and penetration. A 55# recurve was the norm. I started out using a 40# recurve but made up for it with heavy fiberglass arrows and razor sharp Bear Razorheads. My speed was likely around 165 fps! But I did kill a few deer with that combo. (amazingly)
Then came the compounds. Oh the horror! Bows that could kill a deer at 60 yards without any holdover because the arrow could fly so fast (maybe 200 fps) and shoot so flat. LOL
Today our new designs are a blessing in technology and engineering. Bows that launch and arrow at over 300 fps with some getting closer to the 400 fps velocity, weigh in a just a bit over 3 lb, and draw and shoot so smooth they don't even "jump" in your hand at the release.
I am just trying to figure out where the manufacturers go from here. I would guess they are almost to the point of having to develop new materials for limbs and strings as I fear they are at the limits of their stability.
What say you all?

I think that the 400 fps speed is very hight? Can you make it ?
