I killed my first deer, a spike Muley, back in 1965 hunting in NW Colorado with one of my college roommates and using a Winchester Model 94 .32 Spl that I borrowed from him.
I went back with him the next year carrying a soprterized .30-40 Krag rifle that I borrowed from my Uncle. I shot my first elk, a 5x5 bull, on that trip.
The next summer I ordered a Herter's Model U-9 .30-06 barreled action and a semi-inleted stock from them. I got it all finished and hand checkered by deer season that fall, and shot my first 4x4 muley buck with it.
I got drafted into the Army the next spring and didn't have a chance to use that rifle until the fall of '71 when I shot another 5x5 bull elk with it. I continued to shoot a deer and elk with it every fall through 1977. Then in 1978 I had it re-chambered to .30 Gibbs and it became my primary elk rifle until 2004 when a fireforming overload bulged the chamber and broke the etractor.
I had a local gunsmith re-chamber the bulged chamber, but he couldn't completely fix the extractor so that rifle has been retired to the back of my safe, where it still sits today.
