Henry Big Boy 44 with 20” barrel, 1:20 twist (thank you wifey)
The loads I’ve used for the Anaconda, 2400 17.4 grain , were terrible. I have 3 different options a lee SWC 240 TL, a Keith LIKE 255 SWC beveled base, and Lyman destroyer 429640 GC. All powder coated.
I have tried unique 9, 10, and 7.5 with all 3 projectiles. The 7.5 were better but still relatively poor.
I have several powders to try. Titegroup, 231, unique, bullseye, 2400, 296, 800x, lilgun, TCM, and a few rifle powders. Metering won’t matter for this cartridge as everything will be weighed on a validated scale.
My use will be 50-100 yards mostly.
Thank You for your help
