Shoting a TC Endover, Triple 7 FFG lose powder 100g vol., Fusion primers, eather 240 g XTP or 250 gr shock wave. Problem is can't seem to control the highs and lows left and right is great. I feel i'm seating the same depth each time Swabing (cleaning) between shots. Good news is the first shot seems to go were I want it then high then usley back down then high it's driving me nuts. Some might be me but not all. What should I try new to ML. I have some Winchester primers should I try them. Should I go up or down in powder?
