Mac and I have had this discussion before... Leupolds are worth every penny, period! I won't belabor the point, but other than my son's .22 he bought when he was 13 (14 years ago, mounted with a Simmons .22 scope) and my first "big bore", an 1891 Argentine Mauser that wears a Weaver 3X9 AO, becasue it was what I could afford when I was 16, every rifle I own wears a Leupy... No failures, period! Spend all that money to get someplace and have a fogged up scope isn't worth the risk. You can buy better, but you'll pay a couple of house payments and not get much more. But, for the $$$ they are the best. Customer service if it is ever needed is a slam dunk.
For that .30-30... depends on the manufacturer as to which scope... A real nice Vari-X II in 1.5 X 5 or 6 (can't remember) is great for hunting in heavy woods.
I have a Vari-X III 1.5X5 on my .257 Roberts and it is a fantastic deer rifle...
My 7mm, .300 WM, and .338WM all wear Vari-X III in 2X7. My .22 Ruger 77/22 wears a Compact 4X. My slug gun has another 1.5X5. A .30-06 wears a Vari-X II 2X7. My .222R Sako Hvy Brl wears a 24X or a 4.5X10. A Rem 700 in .280 has the only 3X9 (came that way used). And, finally, there is another 2X7 waiting for the new .35 Whelan.
