I read your post and began smiling as I understood what happened . You don't have a Timney problem , Johann . You have a "Jamming the bullet" , problem .

Some "F-class" shooters experience the same issue of pulling the bullet out of the cartridge , if a "Check-fire", or cease fire is called during shooting .
Don't know what bullet you are using , but you might try seating your bullet .015-.020 ( thousandths ) off of the throat to eliminate that problem in the future . I do not "Jam" any of my loads for competition . I believe it causes excessive pressure spikes , and is hard on both chamber , and barrel life . And the majority of the top American competition shooters do not "Jam" bullets , either . The Timney factory is just a few miles from my home , and I stop by there occasionally . One of their techs told me the best way to clean your trigger was to wash it out thoroughly with old fashioned lighter fluid , and blow it dry with low pressure compressed air . Do not lubricate it afterwards . Leave it dry . Hope this helps you out .
