Title: arrow speed
Post by: BWallace10327 on July 17, 2008, 08:25:00 PM
I shoot a #53 longbow with 520 grain ceder arrows.  That set up shoots about 150-155 fps.  Is that enough power for elk hunting?

Make sure they're flying straight and your broadhead is shaving sharp and cuts to the tip, and they'll go right through.

I think it's a little light.  Enough if everything goes right, but it usually doesn't.

My two cents worth not enough mabe sneek up to a elk at point blank you may have a chance try a recurve same poundage and a arrow of at least 600gr 700is better then all you hard work to get close to a elk will pay off good luck whichever way you go if you can only make 1 change go with heaver arrows and scary sharp cut on contact broadheads

I suggest a good single blade broadhead like Zwickey or Magnus and try to keep your shots 20 yds and under. Critical to place that arrow in the vitals and avoid any shoulder hits.

I have a hand written note on "Ashby's Threshold" based on 14.8pounds-feet/second of momentum. The math and the logic behind the math makes me cross eyed, but I keep it as a rough guideline for elk.

weight grains-  feet per second
450-            231
500-            208
550-            189
600-            173
650-            160
700-            149
750-            139
800-            130

What kind of longbow is it? Not trying to put down your bow but it seems slow unless you have a very short draw.

According to the chart, the arrow I killed an elk with last year would not work - 420 gr at 190 fps - buried in the offside leg bone.
Good thing the elk did not read the ashby reports.
