I've been getting some arrow slap (arrow hitting the plate) with some new arrows. They are supposed to be the same spin as my previous batch but are from a different supplier. Can anyone tell me whether arrow slap indicates under-spine or over-spine? Thanks

ttt - help . . . anybody?

Too stiff.

I think you are right bowquiver - but last night I checked in Fred Asbell's book and he said arrow slap indicated an under-spined arrow! I'm fletching up some lighter ones tonight and I'll see the results myself. Hate to think Fred is wrong!

I've had it when my brace height was too high. You might make the arrows work for you if have some leeway in your brace height adjustment.

I think technique has a lot to do with it, too. I usually shoot recurves, and have never had that problem with one. But I also shoot longbows, and have had the problem with several of them. Since I can shoot a series of arrows that are well tuned for the bow (i.e., bare shafts group with the fletched arrows) without getting the slap, and then start getting it with the same arrows, I know it has something to do with my technique. It isn't obvious, though, or I would just stop doing it. I think I just need a really good, smooth release, and not press down on the nock with my forefinger, to avoid the slap. But there have been times I've thought I was doing that, and still had the slap, so it must not take much of an error to cause it.

Thanks for the responses. I've played with my brace height some and that helped a little but not completely. I think form is also a factor because the problem seems to be lessened somewhat when I get a good release (which isn't as often as I would like). But having said that, I never get slap from a couple of my arrows which were made from the same batch. I suspect those arrows were spined a little differently ~ probably on the light side.

For anyone's interest, I shot an arrow spined down 5 pounds last night - no arrow slap the arrow flew like a drunken woodcock and didn't even get to the target. I then took my original arrows and shaved off about 3/4 of an inch from the length to increase the effective spine and it looks like the problem is solved! Asbell was right and my world order has been restored! thanks again to all who responded.
