Guys.
I am going to try an describe what is going on here as best as I can.Please question me if something does'nt seem right.I am only so typing litterate.
I just started shooting and loading for my 280AI,I bought redding FL dies.The rifle came with 30 fire formed cases and 1 loaded round & data using 160gr accubonds.I ran the other brass through the die to decap and resize,adjusted the die so about a dime between the bottom of the die and the shellholder.As I resized I could'nt feel the expander ball like I can on all my RCBS dies but the mouths are nice and round everything looks great.After doing all the other prep work:chamfering inside and out of the casemouth,deburring flash hole.I prime and start loading powder.
I know this seems longwinded but I am trying to give as much detail as I can as we go.The loaded round that came with the rifle was not loose.

I get to bullet seating and there is no tension in the neck of the brass.In all the brass the bullets after being started just push in or pull by hand.The inside dia of the brass neck is .283-.284.The bullets are .283,the expander ball is .282.I took the expander ball/decapper pin out and ran the brass through the resizer bare and the dia came out.282-.283.
There is more neck tension there now but with some effort I can still push the bullet into the case farther by hand.What am I missing?I have loaded for three calibers on two different bullet diameters.Any input is appreciated

One question, Has the brass been neck turned to even the thickness?

I have run across this before, if the necks are too thin the sizing die does not compress the neck down far enough for the expander ball to work properly.

Best wat to test is to try new brass. If the problem goes away, throw the old brass out and start fresh.

Doubt the dies are the problem, my redding dies I have are very good.

280 sizing

I ran into this porblem a few years ago when loading a buddys 22-250 rem.
We were using 22-250 brass once fired,but it was cheap brass made buy imperial.
Same porblem,changed to a better brass and have no troubles since.

Thanx Reb
 
Is your Redding die a bushing type die. Maybe you just need a smaller bushing.
You only need about .002 smaller to hold a bullet, .003 if it is molly coated.
 
The redding dies are just the bone stock FL set.
I have new brass here just fireformed and thats it.Same RP cases.I will try these thanks Guys.RB
 
I had a set of RCBS 338-06 dies that caused the same problem. The portion of the die that constricts the neck was too large in diameter and the case necks were not being squeezed down enough.

In my case the original resizing of 30-06 brass into 338-06 was good as the expander ball was bringing the neck up to the correct inside diameter. Once fired brass however were not being touched in the neck portion by either the die or expander ball.

I ended sending the dies back to RCBS to be replaced.
 
The expander ball is .2827 measured on a micronometer{sp?}.Is 1.3 thousands of an inch within the specs on a .284 caliber die?I will be calling redding early next week.
 
The problem is not with the expander. It is the die itself that has the neck portion sized too large. It is not squeezing the case down enough to be re-opened by the expander.

If you happen to have a 270 case sitting about lube it up good and run it into your 280 die. If the problem is with the expander this case will not hold a bullet firmly. If it is the die that is screwed however the bullet will be gripped solidly.
 
I resized both the new fireformed only 280 and some 270 brass I have.Once seated to length,I can still push the bullets in by hand.
I contacted Sinclair Int. this morning and they have told me to contact Redding directly monday AM.Sinclair does'nt want a direct exchange as all the 280AI dies they have right now are from the same lot.:rolleyes:
thanks for the responses RB
 
RB; You may have misunderstood Boo's suggestion. He was not saying to completely size a 270 case, only to run the 270 case up the die enough to run it over the expander button, then seat a bullet in it to see if the case would hold the bullet. This would let you know immediately if the button is too large, or if the die simply is not sizing the case neck enough. Regards, Eagleye.
 
Ruttinbuck: I suspect your dies were designed to make .280AI cases out of .30-'06 cases.
Cases made this way will give you slightly thicker necks. See if you can find a couple of '06 cases laying around. Run them in and see what happens.
