Best way I've found to remove burrs, it to get them good and wet....
Interesting. It's just the opposite with my dog. If I want to get the burrs out, I have to do it before we give her a bath. It's much harder to brush/pull the burrs out when she is wet.
Arrow tuning is somewhat sensitive to the weight of the string silencers, and also whether they are put closer to the string nocks or toward the middle of the string. There have been times when my arrow has tuned very slightly stiff, and I have brought it back to center by trimming the wooly string silencers.
I just tried to weigh one beggar's lice and it wouldn't even register on my grain scale. I can't find enough of them right now to add up to a grain, but I would imagine it would be 10 or so of them. I don't know how many grains difference it would take to affect tuning, but more than a grain, I’m sure.
I don't know if we're talking about the same thing, but out here it would take 20 or so beggar's lice to add up to the weight of 1 cockleburr, judging by the size difference.
