I need advice on 40mm objective scope for yotes

[outdoorz4me]

First, thanks to all for advice and help. I have decided on a Ruger for my next coyote rifle, standard M77 in 223, it will wear a 3-12x44 Millet Buck Gold. Now, my problem is this: I have a Savage M110 in 243 that is in need of better optics. I have to use extended rings because it is a long action rifle. I am limited to a 40mm objective (maybe 42) with high rings. I hunt coyotes both day and night. So far I am considering a Nikon Buckmaster in 3-9X40 or a Bushnell Elite3200 in same, either firefly or not. How is the firefly for night shooting? Oh yeah, one other consideration, may be the Buckmaster in 4.5-14X40. I made the mistake of not realinzing what a pain it is to scope this long action Savage when I bought it. The rifle shoots great, it's just a little heavy to carry and a little hard to mount a scope on. The other angle I have is that if the scope mounting area is 6 3/4 or more then I wouldn't need extended rings, I can use any height rings. I'm a little frustrated, some help please.

Unless you have a re-barreled rifle, the 243 savage is the short action model, same as in a 7mm-08, 22-250 or 243.  I have a 1967 vintage in 22-250 I use for coyotes in AZ and WA.  I use Weaver two piece mounts with Burris super low Z rings and a Bushnell 3 to 9 X 40 scope, and it fits.  All you need to do is find a scope that is long enough to fit between the rings, mine are not extended rings.  If you use very low rings, make sure the eye piece of the scope is small enough to clear the bolt handle when you pull it back.  Larry
