I shot my granddaughter's Bobcat .50 cal. today with a quartering wind. A PRB with 40 gr. of 2F would not allow any grouping with the 20 MPH wind. I switched to 45 gr. of 3F and it got much better.
It was a good lesson with muzzleloading season opening on Saturday. I'll trick her by letting her shoot 40 gr. of 2F for perceived recoil and then switch it when we go hunting. 50 yards will be the maximum shot I will allow her to take.
