I've made dozens from birch, from tarpaper, to cork gasket. I have one made from a old rubber boot. It's quieter to carry, birchbark is noise. Black can't see it, birchbark especially when rolled the wrong way, white side out is like neon light in early morning or last light hunting. The last 10 or so years I haven't even packed one I do just as good or better with out it.
No one on their death bed ever said; I should have spent more time at work.
got my birch call at Canadian tire. But ya cupped hands work well enough.
Cabelas has them in Abbotsford.
doesnt matter what kind of bullet it is, as long as it weighs 180 grains its DEADLY, even on ass shots....Todbartell-2009
My cousin made me one years ago he lived in PG. We were hunting moose together that year. So he slice around a white birch growing on his property between the knots about 8-10 inches around to allow for overlap and 18 inches long,The bark automatically coiled up then used a leather lace to lace it all together. It actually looked good when he finished As he lived there i left it with him probably should have taken it home with me as he passed away a few short years later i still think of him often. That was in 1980 he actually help me harvest my very first big bull was the best hunting memory of my life.
