Ok, I have been put on hold for a new scope for now. I have a scope that has no dots on the reticle, is there any way to calculate for holdover with it. The reticle does get wider after a bit, is that a certain distance. My scope is a Leupold 3.5-10x40. I will be tested for 200 & 300 yd holdover and this is making me a little nervous.
