Best 300 yd target \"visual\"?? My 48 year old "bifocal eyes" aren't what they used to be. I do almost all my shooting at round orange dots. I want to zero my 300 wby at 300 yds and was wondering if you guys have any homemade ( or other targets) that make it real easy to put the cross hairs onto at that range. (3-9 scope). I can usually get 3-4" groups at 300 but was wondering if there was a better "visual" than my 3" orange dot that would help me hold on target better.
