Bullet seating question
Ok, I am fairly new to muzzle loading. Only been at it 5 years or so, and never spent much time with them. Being mostly a bow hunter I figured "hey this has got to easy". Well I have missed the first deer I have shot at for the last 4 years. I could not for the life of me figure out what the problem was. After some trial and error I realized I am not seating the bullets exactly every time. I have since marked the ramrod and my consistancy has improved a great deal. My question is How important is bullet seating depth. Is it normal to get a 4 to 5" differnce in impact points from a 1/4" in bullet seating depth? My gun is a T/C black diamond using 100 grns of 777 and a 250 grn XTP bullet and 209 primers.
