Just read through this thread and reminded me of a video I saw last week. It was a compressed version of a specialist USA bench rest big bore,design and build video. It showed the precision bedding in process in full. Masked action being bedded into some form of setting plastic and then hand honed to perfection.
Produced a fantastic rifle in the end. I will try and remember company name as it deals with the process you are thinking of doing.
The list of wins quoted for this companies rifles which were "uber " custom high end and v expensive used over long range championships etc. if they think it is worthwhile then why not for a DIY springer project.
