#Are you familiar with the term "swaging"?
Yes I am, if you read my last, "Minnie (sized and lubed)" I do have a .50
sizing die (c/w head & base punch)
BUT
There is a difference between sizing down a cast bullet (Whilst keeping the
head/base profile in tact) and making an FMJ With :-
6 Dia Set (2 Size, 2 Head, 2 Base)
Copper Jacket (Trimmed & Weighed)
Lead Rod (Cut to Weight)
Base Disk / Gas Check (Weighed)
1) Form Jacket to head profile
2) Form Lead to just fit in jacket (at this stage its a slightly long / thin,
but perfectly shaped bullet)
3) Put that in the preformed Jacket from (1)
4) Add the Base Disk / Gas Check
5) Final Press
6) Weigh/Measure
Of Cause making up the Lead with PB Scraper takes less (Press) steps :-
4 Dia Set (inc Std Flat Punch)
Punch/Cutter for Scraper
Phospher Bronze Sheet
Lead Rod (Cut to Weight)
1) Punch PB Scraper from Sheet and Weigh
2) Form Lead to Head Profile (flat base)
3) Add Scraper
4) Final Form with Scraper Base Punch (has slight dimple to allow lead to
"flow" thru hole in Scraper and fix it to bullet)
5) Weigh/Measure
#From experience the steps cannot be reduced for consistent results, step (4)
can be skipped for the FMJ if they are for softer loads, but that means
adjusting the Lead weight to keep bullet weight constant...

R.E.A.L bullets don't exactly have lube canular (grooves) they have ridges
with large valleys between
