Redding Shoulder Bump die

[6MMsteve]

I have a Redding shoulder bump die I tried to bump back some Lapua fired brass from my 6.5284 it made the shoulder area grow, now this use to work on the same caliber 65284 norma savage barrel with nosler & Horny brass it worked great. I have changed barrels since gone to a Shilen 65284 norma with lapua brass, what is my cure call Whidden send 3or4 cases and get a new bump die or is there a quick fix. could you guys help me please

Unless something brand new, Redding does not have a shoulder bump die, only Forester has that in commercial dies.

Redding makes a FL die, FL bushing die, body die and NS only die. None of those bump the shoulder only, as all size the shoulder and body except the NS only die and does not touch the shoulder.

Also, not sure what you mean by "made the shoulder area grow"? Please explain. Wider or what?

A redding body die sizes the whole case, sans neck. What you are seeing is material (brass) moving from lower in the case to the shoulder, pushing it forward. Your chamber is likely a little fatter near the web than your previous one.

guess your right it is a body die might try the Forrester die, might do the job, I guess it flowed toward the neck area thats what it looked like when I dyed the case then chambered it, thanks gonna order a Forrest die

The chamber got cut deeper/longer into the new barrel. If the base of the Redding body die was in hard contact with the topside of the shellholder, then the die squeezing on the case body squirted brass forward since it had somewhere to go, increasing the case’s length from head to shoulder datum. The fix is a thinner shellholder so you’ll be shoving more of case’s length up into the body die, far enough that the die’s shoulder is able to bump the case shoulder back enough to leave it a thousandth or so shorter than the length of new chamber.

That's exactly what the Redding competition shell holders do.,

I believe the Redding Competition shellholders go plus headspace. They are not thinner. Matt

Sorry, Redding Competition Shellholder Sets are sets of five shellholders, one each at .002”, .004”, .006”, .008”, and .010”, all being thicker than a normal shellholder, so that much less of the case’s length gets shoved up into the die.

is there a quick fix.

?

Yes, you can determine the die's ability to size a case, you can determine the distance from the shoulder of the die to the deck of the shell holder. A reloader can size a case that is .012" shorten than a minimum length/full length sized case, the same reloader with the same die and shell holder can size a case that is .014" longer than a minimum length/full length sized case, all of that with the same press.

The ability to size a case for short chambers to long chambers does not prevent a reloader from purchase exotic dies with custom shell holders. My opinion: A reloader should know how to size a case.

I missed it too...

adjustment and shellholders should handle this issue.

Did you call as suggested?

Adjustments and shell holders? The OP started with a problem, seems he was not able to shorten the case between the shoulder and case head. If there is a plan to solve his problem with a shell holder he will have to learn to shorten the deck height of the shell holder.

Before I spend additional money for dies I do not need or shell holders most do not understand I determine if my die and shell holder has the ability to return a case to minimum length, minimum length is what some reloaders call full length sizing. Then there are presses. I have all kinds and types. Some have more ability to overcome the cases ability to resist sizing than others. When the case has more ability to resist sizing than my press can overcome I screw the down further.

After that? I check to see if there is a gap between the top of my shell holder and bottom of the die when the ram is up..
