Howdy,
When it comes to Spencers and Henry rifles, I have a slight touch of obsessive compusive disorder! <ggg>. My goal is to have every book and magazine article about both. My main match rifle is a fire blued Henry Military model in .45. I also had a Taylor's Spencer in .45 Schofield, but that made it impossibl to decide which to use as a main match rifle! I settled it by getting rid of the Taylor's and getting an original. That way I can only use the Spencer occasionally!
I am so obsessive about the Henry that I even duplicate original Henry rounds using 45 schofield Brass, a 200 grain bullet, and 28- grains of BP! It works well in my Open Top and Henry both!
