Have this rifle on the way. A Lyman Great Plains Rifle in 54 caliber. By the date code it is 1980 production. Came with a couple of boxes of Hornady balls plus some powder, caps, cleaning brushes, capper etc. My eyes aren't what they used to be so the sight might come in handy. We don't get the deals here in Canada like Midway was advertising this fall. In fact, it's difficult enough finding one anywhere up here so when this one came up for sale at a decent price I "took the plunge". Now I will likely wait until spring to try it out. Anybody with one of these in 54 caliber have a "sweet heart of a load" recommendation?
