I scope all my muzzleloaders except the flintlock and a couple of Hawkens. I am 68 years old and iron sights are not worth a hoot for me as they are just a big blur. I usually scope my elk rifles (an Omega and an NEF Huntsman) with 1.5-5 power Simons Pro-diamond scopes and usually leave them on 1.5 unless the shot is long and has time to spend changing the scope power. In the trees a 1.5 power scope is as quick to use as iron sights. Arizona allows scopes which is great for me.
