Seems I recall reading that back in the day there were two loadings available for the .32 WCF; a milder load for revolvers and a more powerful load for use in rifles. I haven't noticed that at the ammo store?
Something I noticed when cleaning this rifle is that when you pull off the side plates, turn it upside down, and cycle the action it looks just like the toggle action on a Luger. I would say the 1873 Winchester, the 1873 Colt Single action and the 1911 Colt would be the top three guns on my list for classic goodness.
I have a bunch of 1873 model Winchester rifles and carbines, all in either .38-40 or 44-40. Although I've had a few in .32-20, I've never cared much for this caliber in a '73. I do have a real nice '92 carbine in .32-20. I don't shoot it very often, but it is a lot of fun. Your rifle is a dandy and I'm glad it has a good home.
Beautiful rifle in one of my favorite calibers! I have a model 92 Winchester Carbine made in 1927, a Colt SAA 1st generation made in 1904 and a 3rd/4th generation Colt SAA all in 32-20. They're a joy to shoot! Enjoy your great Winchester!
