FX Shot my MK 3 Today

Mine can sit and maintain poi from the first shot also.
I really think it's because I'm not pushing the gun to it's max to chase high numbers.
I agree with you about not pushing it to the max.....I actually struggled with mine with the poi change after it sit for any length of time as I didn't really know what I was doing with it. It has been a real learning curve getting it figured out, but I can honestly say that I don't have that problem anymore and I absolutely love it now.....I will not get into what I have done to mine to eliminate the problem as that is a highly debated subject that I will leave to those that know more than me....lol
