If I wanted a NF or a March for my SR I'd have one. Certainly not complaining about what I don't have because I don't have it. For the record I have four NF scopes and a Vortex for my F-TR rifles, so you are correct on one count, I don't mind spending money if I'm getting what I want.
I do think the price for the NF and March SR scopes is high for what they are; however, they have built a scope for a narrow market. Guess it's a wash, they need to make money. If there is another option that performs as well I'd gladly use it. Maybe the HiLux will be a complete dog. Their offerings that I've tried for BPCR certainly were, but I do intend to find out this yr. If I find that in my opinion it is a substandard product I'll express that.
There is a foot of snow on the ground here now. The only practice I'm getting is on my SCATT.
My sling experience is certainly limited, of the 11 matches I shot last yr, only 4 were in a sling. I may never shoot a 480 in an XTC match, with any scope, but I can tell when the problems are equipment (not usually) or shooter (most often) and I can tell when something isn't working for me. The Vortex in an example, some people have gotten good results with the Vortex, but for me the reticle doesn't work.
