I've just bought a guide gun in 45-70 and have been working up handloads for it. I don't think I have ever had a rifle - lever, bolt, pump - shoot as consistently well with a variety of handloads. I've put about 120 rounds thru it, and I have already shot 7 or 8 3-shot groups (100 yd) that went 1" or less. This both with 300 & 350 grain bullets, 1-4x scope.
