I've never hunted (yet) but from my range experience,
Well my range experience tells me a 6-24x set on 24 with bags works very well!
BUT HAS NOTHING TO DO WITH HUNTING!!
Most battle sights are peeps, a Large number of old hunting guns were peep sighted...why...because their proven to work!
Ninepointer: listen to advice given, a peep with the insert in forces you to mentally use the rear as an alignment tool, that's OK for target shooting. With-out the insert, you will notice the apature is blurry, that's what is supposed to happen because your not supposed to take time to centre it, believe us it will happen naturally. That's the whole key to peeps you only have two site plains to concentrate on, game & front sight, as opposed to three plains with open sights, game, front sight & rear sight!
