I got some 100 gr. Magnus Stinger, 4 blades this year. I was impressed by how accurate they were. Shot 1 deer with them so far. A rib did bend one of the bleeder blades, I looked and looked and the only blood I found was on the arrow stuck in the ground[&o] But I guess that doesn't matter since the deer took 2 or 3 running steps before piling up for good
