I am using a selfbow I made from Osage Orange, its 62" nock to nock and draws 75# at 28".
I was using a styrofoam-filled target I purchased from Walmart until it fell apart. On that target, I was getting arrow penetration of about 20" or more, even at 75 feet.
With this new Delta Deadstop, I only get penetration of about 2 to 3 inches and the arrows occasionally bounce off of the target!
Is that normal!!
No worries Don. First make sure you are geting good arrow flight with little to no tail wobble. I am betting you are. The difference in penetration is due to the difference in mass/density of the target. As long as the deer you hunt are not made of Delta's material, you sill likely blow right through them. Hte styrofoam material from walmart is not as durable, not as dense and is jsut plain messy with littlewhite grains all over the place.
If you get good arrow flight out of any 70 pound bow, well ... it never ends well for the deer.
