Put your brass wire in a warm oven for a few hours.This will give it a natural tarnish to reduce visibility. Brass is ok for rabbits and squirrels. We used it in Arctic Survival School up in Alaska at Elmendorf AFB.There inevitably will be a few snares broken. Thats one of the reasons you want to set out a good dozen, and eventually upgrade to S/S .Ive never used a fishing swivel,it should work , given the similar weights of the animals.there is a wealth of material on trapping online and in print. Just remember,a person existing solely on rabbit will starve.the meat is extremely lean,so utilize other resources.<br><br>
