Swage on!
New nose size die.
- Thread starter waco
- Start date
It Might Get Loud,is a movie? or video?It features Jack White,the Edge,and Jimmy Page.It chronicles their roads to guitar'dome.Each had a different path.The same can be said for any craft I reckon.So,each shop is going to utilize approaches that work best for them.One of many nuances that keeps interweebness from embracing the true art in any craft.More often than not,guys get their hackles up because they don't understand how someone wouldn't do "X" like they do it.
IMO,one(of a few) of the reasons smaller cals aren't more represented on equipment lists(winner's circles) is the difficulties involved with grinding form tools for their lathes.Grind the tooling that makes cutting cherries,D reamers,etc.... to whatever spec ogive.Compare grinding a .30 to a .22,what did you learn?It's a chicken N egg thing.
The critical dimensions on nose sizing isn't diameter.Once you process one diameter it's a small step(ha)to creating a "range" of tooling...... once "there",you learn why or maybe how a "one ogive fits all" approach,dosen't need to be adhered to.Start with the form tooling,get on with making reamers.In football,it's running downhill concerning ball carriers.But the critical measure is depth control,not diameter control.More downhill running.... everyone assumes it's diameter.Back to regular programming.

I don't know if "secrets" is the right word?
My discipline is first round,cold bore "X"'s.... over a period of days.IOW's,hunting. So,3 shot groups suffice.But those groups HAVE to be repeated day after day,rain or shine.
Next guy,may need to build a load for 10 shot groups to be used in competition. He dosen't give two hoots about cold bore X's.He's gonna shoot foulers and pick conditions to support that # of shots required.
Nuther guy wants extreme accuracy with high economic return.Meaning,least amt of equipment and economy of components(powder).
So,my point in post above was there are different approaches and avenues available to any sport/craft/hobby.Further exacerbated by how ones "shop" is profiled or setup. It's the ole,if you were a hammer,everything looks like a nail syndrome.Our shop is setup to solve problems associated with machining wood/composites/metal.Not,about production numbers.Not really even a niche market.Think,curved high $$$ stair systems.What are the problems most folks run into? That sort of thing.So,grinding a form tool to make a reamer,to swage a bore riding cast bullet isn't that big of deal.Takes a buttload of resources(equipment).I was just shedding lite on certain aspects that some CB shooters may not be aware of,going through "normal" channels.
Look at any tool,gun,part,etc.It didn't grow on a tree.Somebody had to process engineer it?You can pick apart just about any, "this is fact",edict..... but,you can also pick apart just about any process.Knowing your strengths/weakness's is a soft science,but one that's gonna be useful,in our case..... CB accuracy and especially predictability for the hunter.

I couldn’t agree with you more. Making a top punch that will maintain a fine point and not damage the ogive has been a real challenge for me with only a lathe built in 1941. So far the best way I have found is using a dermal with a shape stone after using a rough ground D bit. Hoping to find out if anyone had found a better way. I have tried using liquid steel but it did not maintain dimensions over long runs the way I use them (hammer)

I can guarantee that the CBA BR shoots should be named the CBA swaged bullet shoots.
a bullet swage die is really just a big tapered H&I die.
the chamber throat is cut, then the reloading die, and then the die to swage the bullet is cut right afterwards.
it's all a package deal.
1-14 twist 30 cal barrels abound, and they ain't shy about velocity.

Cool beans Bama,your '41 is right in my wheelhouse!Equipment is an interesting point. Just observation here,but the more interface the user has with the pce,the more,ergo's effect the acc.Compare a moulding machine(wood) where you chunk the wood in one end and out spits an almost finished (needs brush sanding) piece of moulding on the other end to or vs....... an edge sander doing drawer box cleanup.
In the first example there ain't a whole lot of interface,the latter well,depending on the grit uhhhhh we could have a real mess in a very short time,haha.On you nose sizer to die interface,the length of "bump" is the touch or ergo part.Moreso than diameter even though they have an important relationship.One,the diameter,sorta "don't care"(moulding machine)....the length has more feel built in(edge sander).I sneak up on the length bit instead of adding complexity and induced error with making it adj( for length).I reckon shim stacks could be employed for length of bump?But mine are set it and forget it.Just make a new top die if you need to?
