My 99F in 300 dates to 1961. It has the tang safety and hand checkering. I sighted it in last week with a 2 3/4 Redfield scope (58-62) of the same vintage. It also has the big knob old style Weaver rings. It is one of my 100% period correct guns. I was able to get it to 2-2.5 MOA with Remington 150 grain factory ammo. Good enough for my thick Michigan woods hunts. That gun kicks like a ticked off mule!
This is the gun that I found a bill of sale from 1964 underneath the buttplate. I found and contacted the grandson of the buyer from 1964, but he elected not to buy it from me. He was not a hunter or shooter. I only wanted what I paid for it. Oh well, I tried.
