The Rudolph 2.5-15x50 is for sale at Swillington Shooting Supplies for £348, brand new.
That is what I have on my 308 and it’s perfect for woodland hunting, even in low light, for anything out to 150-200m.
Compared with my £800+ delta the optical clarity is as good, as is the light transmission, plus it’s a nice compact scope, not some whacking great chunk of glass adding unnecessary weight to my rifle.
As for buying old and used, would you spend £300 on a well used scope bought from someone you don’t know, with no real provenance or guarantee, or the same money one something that is up to date and comes with the usual guarantees from a reputable retailer?
Personally, I go for the latter. But that is my choice.
As for my knowledge - knowledge is knowing that a tomato is a fruit. Experience is knowing not to put it in a fruit salad! I like to lean on my experience to guide me as to what kit I need to use!
