Any recommendations? I see the weight is in the 215-220 gr depending on pins used. I have th fourth edition Lyman cast book . There is data for a 220 gr hard cast so I have a good starting point. Just want to see what you fellows went with. Thanks

As always I'd suggest you start low and work up.
I have no experience with this bullet in .41 but I have the .44 cal Hammer.
When working up loads in 44 SPL I hit projected max velocities well before expectations, and actually stopped early due to reaching 1075fps ... Glad I was running the lab radar for the initial test.
Based on my test is suspect this particular bullet sits deeper in the case than what I had found for similar weight bullets ... And that might hold for the .41 version.
On another note I would love to know how your testing goes, since I have my eye on this mold.
Thanks,
Freeze

In the process of altering my seating stem. The flat nose stem was cutting a groove around the top of the bullet. I filled the cavity with jb weld so things are at a halt till it cures. Started with 17.0 of 4227. I think ( don’t have the book in front of me) the max is 18.6 . |

But depending on the platform you are shooting, that extra pressure may not be the same concern. My use was in a NM Flattop, so I wanted to keep pressure below 23K (class 2). I know some guys will say the NMFT is safe to class 3 loads, but I'll keep mine a step down. If I need more I'll change guns. -Freeze |
