I have used the 200 grains but just got some of the 150's. I was surprised at how short they are. Any penetration issues? Thanks.  Bill
			
			
			
				None for me. Love them
			
			
			
				I have shot everything from 200 to 100 grain.  All have performed very well on deer for me.
			
			
			
				If you bow/stick is tuned you won't have any issues on deer sized critters.
			
			
			
				They work very well!!!
