Coopersdad, you apply your finish basically the way I do with a few changes. For the first coat I know the stock will absorb finish so I apply a generous amount watching the spots that absorb the most. I continue this until there is no spot that will absorb more finish, then wipe it off with a cotton cloth. BTW I apply finish to the inside of all the mortices and with a q tip to the insides of drilled holes. Then the rifle is allowed to dry a full 24 hours.
The second night I do the same thing as the first night to be sure the pores are sealed, except the stock is lightly sanded with around 400 grit paper before applying the second coat.
The third night I again lightly sand the stock then wipe it off with a damp cloth to remove all the dust possible. The stock was well whiskered prior to beginning applying finish so I don't worry about the damp cloth raising any grain. Now I either use my fingers dipped in finish or a hard cotton cloth dipped in finish to apply the next coat. I make sure there are no runs and the finish is even, then dry 24 hours.
I apply 8 coats of Chambers finish and I let the 7th coat dry 48 hours before starting the 8th. There should be no runs or high spots in the finish at this point. All these I have sanded off during the previous coats.
The 8th coat is hard rubbed until I feel the stock and finish warming up, and here the cotton cloth works well too. I pay a lot of attention to the stock to prevent runs. Holding the stock to a good light will show runs or wrinkles. When I am satisfied I have a good, even, smooth final coat, I allow it to dry at least 24 hours.
Then I rub it down with a piece of Scotch brite general purpose just hard enough to smooth out the final finish.
I don't let anyone disturb me or rush me when I'm finishing a stock.
I like the Chambers finish. My main hunting rifles have been wearing it for well over 10 years with no problems at all. Sounds like you missed a step somewhere.
