John,

This column was really timely for me since I was wondering about my Leupold 3.5-10x40 on my 264 WM. Last week I tried some shooting at 250 to check zero on my gun and 350 yards to check bullet drop in the past it has shot well at even 400+ yards but my groups with the one load were awful. For some reason I decided to check my scope for paralax just as you described and at 350 the crosshairs moved all over the target probably 6 or 7 inches of movement in total. My scope must be in need of repair, I will likely put my Leupold 8x40 AO on it I'm sure it will group better at longer range,I may even leave on their permanently. What do you think of all this?

Thanks.


Gerry.
