I have read of others complaining of sticky extraction/lever and or case head separation and short case life when reloading for an original 1886 Winchester in 33 WCF. This was happening to me with moderate loads with 200 gr jacketed bullets. After firing the lever would be hard to open and the case head would be stretched toward to bottom of the bolt. My rifle is a take down model so I removed the barrel and closed the action to examine the bolt face. After taking a close look I noticed that with the bolt fully forward and locked I could depress the ejector .008" below flush of the bolt face. I then replaced the ejector with a new part from Bob Knapp (Winchester Bob) and found the exact same condition. It is my theory that the case head is basically unsupported by the lower half of the bolt face until the ejector is depressed enough to make contact with the recess in the bolt face.
Since this is the only 1886 I have access to I don't know if the ejector recess on my rifle was cut too deep or if all 1886's are like this. I made a shim out of .008" feeler gauge and placed it between the ejector head and bolt face recess and have fired two rounds of the same load that was previously giving me problems. This time the lever opened normally and the cases appear fine. The load I am using is 37gr IMR 3031, a 200gr FTX bullet and a WLRP in a reformed Starline 45-70 case. I will do some more extensive testing but wanted to get input from anyone with this rifle.
Hornady lists loads for this bullet of 33.3gr to 40gr of IMR 3031. With 34gr I get 1813 fps and with 35gr I get 1912 fps in my rifle, did not chrono the 37gr load.
It would be great to hear from others with 1886's about how much if any the ejector on their bolt face can be depressed below flush.
Thanks for your input.
