Looking good Sean. My own .44's have prefered full charges with 245 to 275gr. SWC's, flat bases, all keith Style, square or rounded grease grooves, no checks using 2400, H110 and W296. Unfortunately, they're hard on my little Smith29, not so with your Bisley.

I've use the 50/50 Alox, LBT Blue, SPG and Lyman BP Gold over the years. All shoot well without and leading in my revolvers. The bullets I shoot are all .430" in diameter to match my cylinder throats & I shoot nothing harder than WW alloys - without zinc. This helps accuracy. Commercial cast bullets are harder and usually lead some as they don't obturate well to seal as-do the WW bullets.
