ormondprop, i have done what you say
bearing in mind that noone else is doing the mag range, so it is impossible to do the 6500 justice (yes i know swaro are now doing a 4-30 but it's £2000)
I have compared my 2.5-16 and 4.5-30 with Swaro ph 4-16, 6-24. Also Weaver Grand Slams, Elite 4200, Nikon Monarch
The 6500 are the equal of any of the top scopes mentioned such as the monarch/grand slam, which is amazing comsidering the mag range. They are not as sharp and bright as the swaros at the top end, not even close.
If i had the money, i'd be buying the swaro z6i series, but at 4x the £ it is diminishing returns in a big way.
6500 series the best performance for the money i've ever seen
