Yesterday I got good results with my Pedersoli 1885 High Wall using Goex FFFg and Swiss 1 1/2. Now I'd like to try some Olde Eynsford and would appreciate some guidance.
The bullet was the Lyman 378-674, 1.312" log, 0.379" diameter as cast, lubed by hand, 334 grains, 20:1 (BHN 10), Federal Large Rifle Primer, O.A.L. 2.9751"
The Goex FFFg load was 52.0 grains by scale weight, compressed 0.3435", Walters 0.03" wad, 2 newsprint disks. Velocity averaged 1,362.69 fps.
The Swiss 1 1/2 load was 44.0 grains by scale weight, compressed 0.0575", Walters 0.03" wad, 2 newsprint disks. Velocity averaged 1,263.49 fps
I wiped between shots with one VFG Felt wad, soaked in Moose Milk, on the dart with a 2" garrison patch trailing.
I have a limited amount of Goex Olde Eynsford 1 1/2 that I'd like to try. What range of powder weights or compression should I test.
Appreciate any and all guidance
