Shot my MGM 18" .357 Max barrel today. Shot great and am glad to know this barrel WILL shoot accurately. Shot a 2" 5 shot 100 yard group with random book load of 25.0 gr/1680/158 Hornady JHP. This with 8X Leupold and a somewhat incorrect target for the power/crosshairs of this scope. Pressures appear very mild.
NOW, do you Maximum handloaders neck size or full length size your cases for a single shot Contender/Encore barrel? I've neck sized straight wall cases before but only for rifle or single shot barrels [not revolvers]. I like to work brass 'minimaly' and now that these cases have been fired in a single shot/chambered gun, and seem to easily 're-enter' the chamber when spun [checking for ecentricity], seem to be candidates for neck sizing only - or sizing the portion of the case that will hold the bullet [I know the case doesn't have a specific 'neck'].
What think? Quit worrying about the details and run it all the way into the carbide die, or just pretend it's a rifle round and size maybe a half inch back from the neck?? Thanks for your thoughts.
