I’m probably going to upset some on here, but I don’t see the point of sticking really expensive glass onto hunting rifles.
My scopes are delta, Rudolph, Nikon and nikko Stirling, with the most expensive being the delta at c£800, and they all perform perfectly for their role, ie enabling me to hit animals at my chosen distances, as well as target shoot out to 600m with ease.
I have also done a lot of target shooting at Bisley and regularly out performed people with serious kit (Sako trg with £2.5k s&b glass on it) with my old rem700 and MTC taipan scope!! So it’s not the kit that makes the difference!
Yes, good glass will let in more light, but would you want to be taking shots at a deer if you couldn’t see what was behind it? I wouldn’t. Plus the normal range in the UK for most hunting is <200m, so in reality a 3-9x40 scope is ‘enough’ to hunt with, and all of the extras are really just to make the shot a little bit easier.
My suggestion would be to go up a notch into the premium normal scope range and see how you fare. If you shoot well and don’t find it limits you then you have found your scope. But simply whacking a grand+ of glass on your rifle won’t make you a better shot!
