I have been driving myself crazy over the last couple of months trying to decide on which scope to get for my first custom rig. The rifle is currently being built by Kirby with the following components: Borden Timberline receiver Wyatts extended mag box Lilja #5 contour fluted, 26" barrel McMillan ADL stock made with Edge technology Jewell trigger Holland QD muzzle brake Seekins aluminum rail base NF Ultralight rings The rifle which will be chambered in 7mm STW will be used for a large variety of hunting with shots from 10 yards out to as far as i can confidently shoot, hopefully 600 yards, or perhaps further. I am wanting to keep the overall weight down as much as i can so i dont want any 30oz NF. Ideally id like to stick to a 40mm obj and i would prefer to keep away from any really tall turrets like the Leupold M1. The new NXS 2.5-10x32 seemed perfect except for the lack of parallax adjustment. There seems to be a mixture of opinions of whether parallax adjustment is needed for 10x, ive heard some very experienced people say that its not needed, but ive had equally experienced people say that it is “highly preferred.” What are your thoughts? Does any one know what size parallax era can be caused at 600yd with 10x? I have also been looking at the US Optics SN-3s 1.8-10x37 with Adj Obj, Ive heard great things about this scope but at 25oz its really a bit heaver than id prefer. All opinions welcome, what scope would you use? Thanks in advance.
