I have a Vortex Viper HS 2.5-10x44 on my 450BM. My only complaint is after the second shooting session the Vortex Sport Cantilever 30mm Mount I used to mount it had come a bit loose and let the scope slide forward a bit. I took it off cleaned everything with rubbing alcohol and torqued everything, so far the scope has not moved anymore. The scope it self is great. I sighted in for 100 yards and recalculate the BDC reticle for my bullet/velocity and glued that to the inside of the flip up cover.
