For years I shot deer with a recurve 45pd bow using the arrows your using, no problem killing deer at close range, then along the way I stepped up to a compound Pierson spoiler 85 pd with over draw using 28 inch 2215 eastons, and one fiber optic pin does all up to sixty yards, use a freeflight release, 320fps, you have to pump iron to get that one back, but in your case I would think about a crossbow, due to your injury, you would still get to archerhunt, but not irritate your injury, The slightest bit of pulling may cause you to reinjure your self again, becareful. Sorry to hear about your shoulder injury, but take care of it, as we get older it seems we take longer to heal, check with your fish and game, you may be able to get a crossbow tag in your state. Take care, and good luck on your endeavors. Aim small hit small. RAMbo.
