RE: slick trick blood trails
Shoulder shots don't bleed much no matter what you use. High under the spine shots, don't bleed much no matter what you use.
I have used so many BH's its not funny. And if you hit in the lungs behind shoulder little low from middle. They will bleed.
If you shot that doe thru the shoulders with a large rage or spitfire, most likely you wouldn't have found that deer.
