I was cruising the auction site we all love to hate for bullet molds several months ago and noticed a bullet mold that was advertised to be used with a coil of wire to be placed inside the mold before casting.
I haven't been able to find out anything else about this type of bullet but I could see some potential for the idea. The mold cavity appeared to be smooth inside and did not have any grease grooves, so apparently the bearing surface between the bullet and bore was the spring wire and whatever lead filled in the spaces between the coils.
I wonder if this might be an idea worth investigating. I would bet that using square cross-section copper wire would act nicely to scrape the bore clean w/o damage, and if it would allow softer alloys to be used it might make for a more effective game bullet. It might also make for easier-to-machine mold cavities. I suppose a gas check could be incorporated.
It might be more trouble to cast, but if it cut out the lubing/sizing process it would probably be a wash.
If anyone has any information or thoughts on the matter I would like to hear them. I've learned an awful lot from reading the posts here and really appreciate everyone's opinions.
