I am hoping to find something resembling published load data for the long time discontinued Lee Mold 90343, 429-255 SWC. Apparently Lee used this same number (90343) for a 401 mold at some point and it is now used for their 7mm-08 trim die. Older info discussion here: https://castboolits.gunloads.com/showthread.php?57777-Lee-90343
It is plain based and as cast weight is 266 grains using COWW and is/will be powder coated. For now I plan to run it in a Ruger RH.
I am mostly flailing around trying to nail down COAL and starting loads and thought perhaps some load data is to be found in some older cast bullet reloading publication/s or possibly in 'The Complete Reloading Manual for the .44 Magnum'.
If I seat to the crimp groove there is a LOT of bullet stuffed deep into the case with a 1.605" coal. If I seat at the first of three shallow/narrow lube grooves I get a COAL of 1.710". Held beside a Keith style bullet, at the lube groove the amount of seated bullet is quite similar and it still plunk chambers in my Redhawk (but not in my Dan Wesson).
Since I have most of an 8 pound jug of IMR4227 sitting around without a mission, I plan to start with it. If that doesn't pan out I have limited quantities of H110 and Unique.
FYT, I posted a similar request for information on the firingline forum.
edit: added bullet pic alongside the Keith style, RCBS 44-245-kt, as cast 249.6 grains, with COWW.
edit @: updated pic showing both 1.605" and 1.710" COALs.
