My Redhawk 7.5” runs 1176 with an SD of 15.
If one looks at what Elmer Keith was lobbying the manufacturers about was he wanted someone to make a 44 Special Magnum load in 44 special cases. The load he was requesting was a lead boolit weighing 250 grs. traveling 1200 FPS at the muzzle from a 6.5” barrel.
The HS6 load that is being posted here in this thread comes surprisingly close to Elmer’s dream load.
When Smith & Wesson released the 44 Mag on the market and through the years of the Dirty Harry era a lot of revolvers were bought with a box of shells. The owner would go out to field or range and fire a cylinder or two of the heavy factory loads and bring their prize home and put it away never to be fired again! Too much pain and likely some fear.
What was needed were some factory loads of differing power levels for shooters new to large bore magnum handguns. I would be surprised if a load for the 44 with the dwell time and other attributes such as the load being discussed here would not make the top tier of ammunition choices.
