looking at a vortex viper hs 2-10 or 4-16 BDC reticle. my question for someone that has one is-how visible/dark/contasting is the reticle? it looks like the crosshairs are fine plex outside the BDC (ranged dots)which also seems feint in pics on differnt sites. my concern is seeing when hunting,say,against darker wooded background. fine would be ok when using the rig on paper. it's SFP so reticle won't change size at any mag. thanks.
