I had already shot about 50 rounds of 44 mag in the BB over the chrono before I got to the 45/70. So I was getting a little tired. Not an excuse just stating that. The sun was also in and out of the clouds which affected my point of aim. 1st target was 2 groups of 5. 1st 4 in the center were shot under cloud cover. Last 6 the sun came out bright on the target and the difference shows. I was little surprised myself at the POI change.
Henry 45/70 brass, Skinner rear sight with .040 aperture and Lyman MJT 20 front globe sight.
All cases neck sized to .459".
10 rounds
300 gr Missouri Bullet Co. Coated FP. .459"
12 grs of Unique. WLR primer.
My rounds averaged 1,163 fps.
Pretty much 1 3" group and 1 at 2.5" @ 50 yds.

5 rounds
405 gr Missouri Bullet Co. Coated FP. .459"
11 grs of Unique. WLR primer.
My rounds averaged 1,023 fps
2.75" group. I think this bullet might shoot tighter at a higher speed with a different powder.

5 rounds
350 gr Berry's plated FP .458"
11 grs of Unique. WLR primer.
My rounds averaged 921 fps
3.25" group @ 50 yds. I'm thinking these might do better neck sized to .458

All rounds were very pleasant to shoot recoil wise. No fouling in the barrel.
