I used to just use a 10X SWFA for said purpose for years. As my eyes got worse and I finally needed glasses, I switched to an SWFA 5-20x50 SS HD for my scope against which all others were judged, all rifles were tested and load work-up was done or, more appropriately, as stated by Al above. I now have so many SWFA, Athlon Helos and LRTS/LRHS that I trust, it just doesn't get used as much any more.
