I'm not gonna worry about that any more than I'll sit and sweat worrying about getting hit by a bus tomorrow. I don't have any .44Spl's that won't handle the Keith load anyway.....and probably never will. And it's not like I keep thousands of them loaded at any one time anyway.
"Can't control what will happen to your reloads. " Yes, point well taken.
The best he could do is label the boxes they are in and perhaps put a label inside the box and hope for the ballistic literacy of whoever winds up with his legacy. A red warning label stating that they are "Ruger Only" overloads as well. But there is no way to guarantee results short of simply using magnum cases.

Exactly. I want to shoot my Blackhawk more often and in the comfort of A/C until the temps drop into the 90's. If I am going to shoot specials, I don't want to be limited to 5.7 grains of Unique like I use in my Taurus 445 ultralight with 240 LSWC. My concern is mostly about brass life and flying steel projectiles. It only makes sense that any load in a 44 special is just fine in a 44 mag firearm, however, going from a 13 grain max up to the 17 grain area is a bit scary for me as I have never ventured off the path of up-to-date load data. I will load some ammo up Wednesday morning and plan to go shooting afterwards. I don't have a chrony so I can't gather any empirical data.
Should I use magnum primers for these loads?
I will be using hard-cast 240 grain lswc with 2400. Starting grains at 11.0 up to 17.5 with .5 grain intervals in Starline thrice fired .44 special cases, heavy crimping at the groove.
44 Magnum pressures inside a 44 Special case will not cause the brass to fail if the chamber does not fail. That 44 Special Case loaded to Magnum pressure will not rupture a 44 Magnum chamber, but would endanger a 44 Special chamber. The 44 Special cases are constructed in the same manner as 44 Magnum cases, just a little shorter to prevent chambering in 44 Special firearms. The brass fails AFTER the steel fails (absent some inherent weakness in the brass or chamber dimension fault, in which case EITHER Special or Magnum brass is equally likely to fail).
The
caution is that the shorter case of the Special brass will result in higher pressures than if the same powder charge were placed in a Magnum case (and be sure to note that the relationship is NOT necessarily linear).
All the foregoing is to say that your caution "going from a 13 grain max up to the 17 grain area is a bit scary" is well-founded.
Unique does not require magnum primers. Unique is easy to light. Mag primers are for hard-to-ignite powders or densely packed powders through which a flame front might have a hard time traveling.
I only apply a strong crimp if I get crimp jump or am using a powder that requires a high pressure for an even burn. Someone who knows more about Unique can check me on this, but I don't think either is required with Unique, so I don't apply a tight crimp to those loads. Also, in a heavy gun, crimp jump is less of a problem than in lighter guns.
