Eagleye, you sure know how to bring back the memories. My 1956 Model 94 had a Williams Fool Proof aperature and a fine gold bead on the front. To get my bullets to drop into the area of the ten ring, I just rested the bead on the top of the shoulder on the three hundred yard goat.
There were five targets, a running deer at 100, a running antelope at 150, a bear at two hundred, a sheep at 250 and the goat at 300. You assumed any position you desired, usually prone, but no rest allowed. You had five cartridges and on your signal a target was called up. The shooter had no idea which target would appear, until all five had been shot at. The pop ups stayed up for four seconds.
The course of fire for most events was any rifle of 243 calibre or larger and any sight.
However, I was on the rules committee at the Salmon Arm shoot and it was actually me who came up with the idea of the "Frontier Event." Rules were any lever action rifle designed before 1900 with iron sights. As Dave has said, I think everyone used a 30-30 for it.
Eagleye shot with us at Salmon Arm, so we competed. Dark Alley Dan, on the CGNs, came from Albera with his family as a sub-junior shooter and his Dad and I had some prettty good competitions. Many of the shooters, usually familes, came from Alberta.
Over the years at the Salmon Arm shoot I won first in the Frontier once, twice I got second and one year third, in the Frontier Event with the 30-30.
I also won some trophies in other events with my 243 and 270.
Here is a picture of my trophies won at it the Frontier in Salmon Arm.
