I have a 67 94 Candian Centennial rifle (26"), using a PC'd, 158gn. (Ordered from supplier), and a Lyman 311466, (coated & lubed). Used IMR-3031@ 22.5 w/ 158gn. OAL 2.552
Used IMR-4198@18gn. w/158gn.OAL2.510
Used IMR-4198 @18gn. w/158gn. OAL2.530 -----------------NONE, of these could find 3" bull @ 50yds !!!!!
All shot's "LOW LEFT", were talk'n 8-10" low & 5-6" left, but not as a groupe.
Got up early, drove to range, fired 1 factory 150gn., Bulls Eye (well the barrels not bent), then fired 1 rd. 158gn w/ 18gn. IMR-4198 (shooting West), (it should be about New Mexico by now), hit low left corner of target, (maybe the targets don't like coated bullets???) Ya' think i need to up the charges? Chrono showed 1750's
hav'n coffee, Hootmix.
