Now that it has warmed up I have been shooting my 1894 with its new 45 Colt Micro Groove barrel this week. I have been loading 250gr Dardas RNFP with both Unique and Trail Boss. So far 5.5gr of TB holds the best groups but always shoots 3 to 4" to the right of my Unique loads in the 8.7 to 9.0gr range. I am just wondering what is the cause of this consistent shooting to the right? I have never really experienced this with just a change of powder before. All else is the same, trim, seating depth and OAL, bullets, primers and brass.. I really need to get the Chrony out and see what it is saying.. Any insights?
