Long GC shanks VS Newer Cartridge Case Designs

In looking at the traditional cast bullet designs one tends to see longer cast bullet Gas Check shank lengths that were technically appropriate for the older long necked cartridges that were around when those cast bullets were designed …

Long cartridge case lengths tend to equal long GC shanks as the cast bullet design … Which … Can potentially be utilized as yet another lube grove…

Unfortunately the newer cartridge case designs tend to be of the shorter necked variety, & in order to meet the max COAL of these newer cartridge cases one appears to be required to seat the with its GC well down into the cartridge case body… That tends to expose bare alloy above the CG to the powder.

In addition if one is still utilizing the older brand of lube … one tends to risk the exposure & contamination of the powder charge in the cartridge case to the lube utilized on the cast products long GC shank.

Thus one has several possibilities open to those that are trying to satisfy … their firearms need for literally their own private brand of cannon fodder to feed their hungry firearms.

One possibility might be to take those longer GC shanks, & make them shorter…

That can potentially be accomplished by either milling down the face of the older mould designs …

Or by in the designing & cutting of those GC shank lengths down so that they are just long enough for their tiny copper bottoms to fit… & no longer utilizing those longer GC shanks as another potential lube grove… When machining the mould cavity…

One then also needs to think about the possibility of nose sizing those cast bullet designs … lest one consider cutting up a treasured firearms barrel to ostensively add more freebore (or any other of the numerous names that SAAMI or CIP might come up with as a descriptive term for the preface to the start of the rifling…

This might be a potential path towards eliminating the older GC long shank designs, & a space for the older lubes to hide in and then contaminate the powder charge in the loaded cartridge case… causing erratic burning, & etc… opening up fired groups…

So what is the solution here?

If one were to advocate going to a powder coat that might be a potential solution … up to a potential limited terminal velocity … before one might tend to get some leading going on in the firearms barrel. That unfortunately not eliminate from those older designs that were put into place when Holy Black was the only game in town and exposed lube on the cast products nose was exposed to the sand and other debris in the course of time between cartridge assembly and the projecting of that cast product down range with its rock had debris potentially marring ones rifling…

If one were to design and make up a taller Cu or Al litho GC to more completely fill those longer GC shanks that might also allow those older cast product designs to once again be seated..

One could potentially go as far as to design a cast product in the form of a lead core that could then be put into a much longer GC or even a brass cartridge case… (Incidentally that requires pure or almost pure Pb to go that route… Do not try this with a harder alloy lest one wishes to see if one can destroy a swaging die with a 50 ton press.

Some have taken to the idea of using once fired 22 rim fired cartridge cases as a basis to form a much longer jacket for said purpose of essentially making fodder for ones hungry cannons in that caliber… That tends to require a set of forming dies to iron out the rim fire rims and to make a smooth sided cylindrical case for the lead cores to fit into.

Unfortunately one might now also tend to need a 50 ton press to swag those components together …

OK lets go to a slick sided powder coated cast product … That will also potentially work until one gets to the point of advocating a GC bottom on those slick sided, & powder coated cast products … Cu (copper) Al (aluminum Lithograph plate) seems to be popular at the moment…

So one guesses that each of us will pick the path to what we each individually consider to be our nirvana of cast products and the method of driving that end result down our cannons (hand cannon or an other wise longer version of the same) to satisfy our love of the smell in the air …

It may just boil down to our individual perception of the perceived Victory … on our chosen path to feeding our hungry cannons Cast product lead fodder (in ones chosen form or another…)

OBTW if perchance I have left out your chosen path … to shooting Nirvana … I do sincerely & humbly apologize.

Take Care, & Stay Safe…
