Well, I thought I had just joined our BBS friends sniper club. I cleaned the barrel on my MarkII TX and the first 3 shots made a hole that looked like a TicTac shape. The next shot was about an inch higher and left and #5 was even more off, so I was kicked out of the club. Of course, I was only shooting at 55 yards, from the knee, FT style. Yet another vote for the three shot group.
