I love me some Winchester 100s. Currently have 4. Pre 64 243, post 64 308 and 284 and a carbine in 308. Ive owned a dozen. Ive replaced the firing pins on all of them. Takes me about 15 minutes to take one apart. I send the old pin off with the serial number and Winchester sends me a new version with a check for $35 I think. Accuracy is deer killing accurate. Not a bench gun. Just make sure the rear trigger guard screw is tight. If the screw gets lose the bolt can over ride the hammer and cause big issues. I see a lot of 100s with busted stocks from either someone trying to disassemble one improperly or the issue with the bolt over riding and the person not knowing how to recock the hammer.
