I have a new Spencer and have started to shoot it...here's some info and more to come as load is developed.
56-50 cal.
The Spencer is complete, I have the original breach block too. address is mostly there, back half weak front strong 1865 date Prov mfg. . cartouche is visible too.
low serial number. 193x. any idea of date of mfg?
the bore is really sharp. three groove 1865 type.
The Stabler locks up with the center fire breach in and won’t close when opened. It catches. I just lock it open anyway. probably would be fine with the original breach, but no matter.
load, 340 RNFP Lyman, 35 grains 1 1/2 Swiss, one card, SPG lube by hand, 515 diameter, straight from the mould. . 1.58 TCL accurate, 3 inches at 50 yds. but more testing to be done. had to raise front site by adding german silver. easy to do.
I tried adding two paper wads under bullet, but both with and without are good, so wad doesn’t seem to be sticking to the bullet. base of bullet wiped before loading anyway. That's a must!
I want to try the 515 lube sizing die when it comes, and expand the cases to better ease the bullet in the case.
The 512 expander is just not enough. At 512 sized, it’s accurate four out of five, but always with one flyer.
bore is 515. so it needs the larger size I would think.
