Range card off after switching bases
I switched scope bases from a 0 moa base to a 20 moa base recently. I zeroed the rifle for 100 yds and now it seems that my range card is off. Bullets seem to be hitting high. Just wondering if anybody has seen this happen after changing bases. Possibly due to the scope and bore alignment being different than before. Savage 10 fcp hs in 308. Nightforce base, mark 4 rings, viper pst 6-24 x 50 ffp scope. This is the same range card I've used with this load for years.
