The 6500 Bushnell is a 4.5-30x50 Sidewheel scope. Takes a bit to get used to for ranging but worth it if you benifit from the light weight about 12oz less than the DMP and compact size. I can match a Leup comp on every target with mine but have used it for a couple of years.
The 8-32 Bushnell is a 4200 series, again about 12oz less than a DMP but front paralax. Probably the best optics of any scope under £1000 if you can live with front Paralax.
I can let you try them both compared to youre DMP at the Greyhound if you let me know when you are there.
Make every shot count
