I haven't used the illuminated reticles, so I can't comment about those.

I have used the Leupold Vari-X III's in 1.5-5x, 1.75-6x, and 2.5-8x's. On a rifle like the 416, I think I would prefer the 1.5-5x, though I really like the 1.75-6x also. My No.1 S wore a 2.5-8x for a long time and it's a great scope also. Probably more weight and magnification than is really needed for the 416.

The single-set Kepplinger can't be bumped forward until the safety is switched to the fire position, so the likelihood of it getting bumped forward is remote, but can happen. To me that pretty much means you would have to have your finger inside the triggerguard before you push the safety off, or before you are ready to fire, a very bad practice. If you handle the gun the way you are supposed to, it won't happen. Doesn't mean I don't check it from time to time.

I wouldn't think a 'smith working the trigger over would cost more than $50 at the most, and it can give you a pretty good trigger, on par with the Moyer from what I've heard.

John Barsness did an article a few months ago where they have subjected several scopes through a battery of torture tests. The lighter weight Leupolds came out on top with heavy recoiling rifles. The 1.5-5 and 1.75-6's lasted longer than all others. He even included some blurbs by Kenny Jarrett, D'Arcy Echols, Charlie Sisk, and other custom rifle makers. All seemed to agree that for heavy recoiling rifles the Leupold 1.5-5 and 1.75-6 were as good as you could hope for.
