I put a Burris 4.5-14 ballistic plex on my 338 RUM. I am shooting the 225 AB (BC .550) at 3050 fps. I zeroed at 200 yds with a nice 0.79" 3 shot group--I love this gun! I shot 3 shot groups at 300, 400 and 500 yds and my drops were dead on with the hashmarks on the scope. I did not have enough space to shoot 600 yds which would correspond to the bottom duplex on the reticle. I know that these marks are not going to match up at even distances for every load combo but it is nice that they match up for mine. This reticle is not cluttered looking and the hashmarks are small enough not to obscure the target at longer distances. I'm not ready for dialing in my drops at this point. I'm afraid I would forget where I was at. I'm still learning on doping windage at this point. Just thought I would give a little report on my experience.
