Long time viewer first time poster, looking for some help with scope selection. I'm about to switch from a Swaro Z3 3-10x42 BRH to a Z5 3.5-18x44 BT 4W on my 300 wsm. I really like the thickness of the BRH reticle and I'm concerned that the 4W may be too thin. I'm not able to look through one so I'm hoping someone can chime in with their thoughts on the 4W, ideally compared to the BRH. Primary use is hunting so ability to see the reticle in low light is a must. Thanks!
