What's your favorite, accurate target load for a 44 mag? I'm trying to help a buddy find something to use in his new Readhawk that isn't a full-bore Magnum load. I have never had to mess with one of these before.
I don't have my reloading logs with me but my first suggestion would be to use .44 special loads. I use a Penn 200gr RNFP in special brass with my SBH and even at 1100fps it is a powder puff in that gun.
But you can use standard 240gr bullets in magnum cases using fast powders. One would be Unique. Check the Lyman #48 manual for suitable loads with other powders and bullets.
My most accurate load is 240 gr gc cast over 20 gr of 2400. This isn't an easy does it load but the one I use for hunting. A load with a 240 gr cast bullet over 8 gr of unique is much more sedate a load for targets and plinking.
Albeit a bit smoky, somewhere between 8-10 gr. Hercules Unique under your favorite 240 gr hard cast lead swc bullet with WLP primers will produce great accuracy and deliver satisfactory mid range performance levels for most 'plinking' duties.
I find that the 7.6 grs my old bushing measure drops of Universal Clays under a 240 gr SWC bullet is very accurate and not near as smoky as Unique. For just a bit more power, 8.5 grs of Universal with the 240 gr bullet also works very well in MY gun.
Been out of reloading for over 20 years, but back then I don't remember using such small grain weights (assuming the quailities of Bullseye and Unique are near the same) in a large caliber case.
I didn't reload for 44Mag, but a friend of mine did. The first 44Mag I ever saw was his and thought is was too much of a cannon. Backed up a little every time I saw him pull it out. Backed up even more after I saw him reload by scooping 2400 with the case and compressing the load. Don't remember the bullet weight. Guess it was a good thing he had a Ruger.
