Installed Viper MRD sight on my Garand .308 Navy SN 7100---. Used Hopco mount $99. Mount swapped out easily and red dot mounted perfectly. Will develop cast loads with this sight because it is more precise than the stock iron sights. For competition the sights can easily be swapped back. More news as I develop loads. Will try spitzer /bore riders 170-190 grain gas checks, ex. Lyman 311334, RCBS 208g Sil and Lee 190gr. WW/2% Sn water quench size 0.310. Powders Varget, 4227, 5744, H322. H322 popular at CBA BR competition. Any thoughts on Garand .308 loads RSVP.
