I was shooting 300 BO with Barnes 110 gr TAC TX hand loaded. 16" barrel. Shooting 1.5 inch MOA at 100 yds. Went to check the feeder the next morning and blood was splattered onto the housing for the battery and timer compartment. I alternate between Barnes 110 gr and Hornady 110 gr V-MAX. V-MAX at higher velocity does good too but I have a bit more confidence in the Barnes but they are expensive vs VMAX.
