Found some bullets from long ago (before I ever had a 44 Magnum: my pistol is a Ruger SuperBlackHawk Hunter.)
The bullets are 300gr Federal lead WFPGC. Cases will be new Starline with Remington Magnum LPPs. Anticipated OAL is 1.640".
The plethora of variations in so-called "Published Load Data" for 300gr bullets is downright baffling! Without getting into too much detail loads for the exact same bullets at the exact same OAL with over a FULL GRAIN of ADDITIONAL powder charge can vary 125fps, but in the WRONG DIRECTION!
i.e. Hornady 300gr XTP at 1.600" using 20.1gr H110 = 1200 fps per Hornady, the bullet manufacturer. The same bullet, same 1.600" but with 19.0gr of H110 = 1325fps(?) per R. Lee.
This hard cast gas checked bullet most closely resembles the Lyman #429650 (a discontinued SWC) for which there is LYMAN data, 18.5gr H110 but at 1.700" (!) but only 1036fps.
I only have 18 of these, which are probably enough to last me a lifetime (unless a herd of elephants or a sloth of Griz decides to invade the Ocean Shores peninsula) if I don't burn some up in load development. Don't want to wienie-out (Buffalo Bore's 305gr version is 1300 & Grizzly's at 1400fps!) TOO much, though...
So... How does 20.0gr of H110 @ 1.640" (OR 19.0gr of IMR 4227) sound?
I appreciate your kind consideration in advance!
Cheers!
