My .300WM SPS has a Wotac 6-20x 50 Mil dot on it and has taken the pounding from that round nicely. Met with the builder Matt and he reassured me the scope would perform well on that rifle. Not sure where Matt ended up and I know he had some quality and service issues but it would be nice to let him know the one he built for me did everything he said it would and exceeded all my expectations. Since then I've tried Primary Arms 4-14x 40 ACSS reticle on that rifle and my 700 AAC in .308. That scope is Awesome for a $275.00 illuminated scope! check them out online and you'll see what I ,mean. Sorry for sounding like a commercial, but I've tried a lot of scopes in my 50 years of shooting including Leupold, Vortex, Nikon and Nite Force.
