I read all of the old posts on bullet size and amount of powder to use but i was wondering if i could ask your opinion. My friends dad taught me to use 3-50grain pellets of triple 7 every time. From what I've read from older posts this is overkill. I am planning on buying some t/c shockwaves and hornadys fpb to try them out. Any advice on the size and amount of powder to use? I can't imagine on making any shots more than 100 yards where we hunt. Any idea as to why he always uses 150 grains? He has been hunting for a long time and knows a lot.
