Kurt,
Here are three bullets I've mentioned recently, all .44 caliber, from left to right:
The first is the GG bullet that gave me very good and consistent accuracy out 600 yards in my .44-100 ST. It is similar to your pp silhouette bullets.
The second is from my new BACO nose pour adjustable .44 caliber mold. It should shoot well in my .44-77. Not real high BC there either.
The third one is from the mold I cut a couple weeks ago with my home made 4-flute cutter. I cast a few the other day while the pot was warming up just to get an idea how it looked and if it would be worth putting more time into the mold. I think it will be. This bullet is a .44 caliber version of my very accurate .40-65 pp bullet and I have sent computer files to Rick at KAL T&D to eventually have him cut an adjustable mold to cast this bullet. I have used this design in a few rifles now and it shot well in all of them. Most notably in my .40-65 where it has held up well in some ugly winds for silhouette and mid range. It's really just an old Sharps design, nothing new.
