Have any of you guys had trouble keeping your FF3 sighted in? I bought one last year and fell in love with it. I shot and missed a bird with it soon after getting it and had to reset the aim on it. Then this year it seems to be shooting 6" low again. It isn't constantly moving but it seems to move every now and again. Any ideas?
I am using a Sumtoy mount on my SBE 3 and it seems VERY solid.
