Ever have a gun that tested your accuracy load development patience? I have one -- a Uberti 1866 sporting rifle chambered in .38 Special. Luckily, it didn't take too many range session to find an accurate jacketed load with
5.1-grains of SR 7625 and Sierra's 125-grain JHC, but four or five years later an accurate cast load has been frustratingly elusive. Various amounts of Unique, Bullseye, SR 7625, 2400, etc. have all been either no-gos or what shot well once was not repeatable. Too, iron sights are becoming ever more difficult to accommodate my vision. Or the other way round. I've had many thoughts of selling the rifle, but it's a fun gun and even its most inaccurate loads are closer grouped than the widely spaced patterns of the AR blasters. Also, I'm not ready to end the challenge.
Not having any satisfying results with HS-6 and the .45 Colt Uberti Cattleman, .the 44 Special S&W 624, or the .357 Mag. New Vaquero, I decided to test it this morning with the 1866. Yes, it's only one time and five shots and it may not seem like much but taking all of the first paragraph into consideration I'm smiling.
50-yards, 5.5-grains of HS-6, Lee's 358-158 RNFN (de-bevel based), .655" East/West .911" North/South
