Impossible Shoulder bump?

[LynnJr]

I have read here many many times that it is impossible to bump a shoulder with a full length die.

So if I buy this brass with no shoulder it would be impossible to put the shoulder were I need it?

If the shoulder was 0.001 to long I would have to throw it out because it can't be bumped back?

How can these large companies sell brass that can never be used?
And then there was the time my straight edge and feeler gage fixed my shellholder.

Hmmm.... cam-over press, or no?


Once upon a time a reloader used a straight edge and a feeler gauge.... no, wait.... tensions - yeah, that's the ticket, tensions.

I can see everyone is breathlessly awaiting the explosion.

I'm concerned if it's going to have 18 neck tensions or 19 neck tensions. God save us all if it turns out to be 20.

This solve my 458 Lott brass problems.

Only from one guy, though.

If you wanted to form that into .223, how would you do it?

[kcheung2]

Whomever thought of that idea is a marketing genius. Eliminate some of the manufacturing processes and thus lower the cost, but then charge 4x more because it fills an unmet niche.

Not exactly new. Remington manufactured and sold unformed cases based on the .308 cartridge some 60ish years ago, specifically for wildcatting cases. That spurred the birth of the 6mm Benchrest family of cartridges, among many others.

No wonder neck turning was a thing back then!

You neck down the 308 case body from ~0.450" down to ~0.275" and the wall thickness becomes THICK.

I wouldn't, it's for forming into different calibers that don't have readily available brass.

If I was going to waste one case as an experiment, I would anneal it first. That blank brass is close to 35 caliber (that's what the 35 Legend looks like.)

So I would run it in a 300 Whisper neck sizing die, anneal it again and then a 6 mm TCU neck sizer, ream the neck to get rid of the thickness, anneal it again and then run it through a 223 neck sizing die and then inside neck ream it again.
