I had an order for some PP boolits so thought someone might find my method interesting.
These are 650gn 50 cal pure lead
Paper is 100% cotton fiber resume from office max.
They are run through a .512" sizer. You can see the base petals are pressed tightly and injected with lube and the patches are ironed on tightly. Maybe you cant see but there is a very thin film of lube on the patch. I have been doing it this way for 20 years and get excellent accuracy. Have taken moose, caribou, mule deer and grizzly, are ya ready for this carpetdude, all with one shot each.
I have done this with many of my 45 cal grease groove molds sized down to .452" and patched up to .460".
Have also dont it with a variety of other cals like 270/284 25/26 338/348 348/358 and so on.
I offer patching as a service for .05 ea..
