Post and crossshair. I have a Weaver K 2.5 on my M600 358 for just that. Old gun, old scope.
^^^^^^ This ^^^^^^
I'm pushing 70 and can still use a standard duplex no problem but the Post/Crosshair is where it's at as far as I'm concerned for whitetails in heavy cover. I have a Marlin 336 in .35 Remington with a Denver Redfield 4X post & crosshair scope and a Remington 760 pump in .35 Remington with a Denver Redfield Widefield 2 & 3/4X with a post & crosshair.
Have a Denver Redfield Lo Pro Widefield with the tapered crosshair which I find impossible to see in low light which I sent into Iron Sight Inc. to have rebuilt and resealed. For an additional $15 they will change the reticle to a post & crosshair so I am having them do that too. That scope will go on a Remington 760 in 30-06.
