i have used muzzys for years and my cousin who is a guide got crimson talons as a sponsor 2 years ago and told me about them last year so i switched to them and i love them. i have not had a deer go further then 30 yards from impact. we have a dmap stamp for our county and last year on our farm i harvested 14 deer with the bow (12 went to hunters for the hungry) and every shot blew the deer up like a gun shot. my best shot was a doe at 48 yards that i shot in the head and it blew through her skull and stuck in the ground 6 inches. now they arent as tough as muzzys but for 30 bucks for 3 they are worth it cause you wont loose the animal. you will have plenty of blood if you even have to track the animal but like i said i saw every deer drop within 30 yards of the shot and expire fast.
