Shoulders Problem

[L.Sherm]

I had to grind .010 off the top of the shell holder on a 300wsm FL Redding die to get any bump. That being said chuck the nickel brass and get you some ADG or Lapua and don't look back

What press are you using? And part no. of the die sets being used?

 

[slydo]

At the top of the stroke, the shell holder and fl die must be in full contact, when sizing.

Screw fl die down more.

It's touching the shell holder + 1/4 turn
Told you first ... Read, view, and try everything ... I'm not a machinist but a damn good mechanic
Just don't understand WHY shoulders are so forward 0.010" after shooting

 

[LCazador]

It isn't going to matter how much you take off shell holder or die or how far you screw it down. You're way past standard dimensions. Even a good mek and ick knows that! LOL

 

[slydo]

Almost looks like the wrong die

Or using the wrong ammo in that chamber

Lol... Wrong ammo lol... Rifle shoot moa with those ammo

 

[slydo]

Lee press with RCBS 30801 die and Lee Can't find part # set of FL + CRIMPER + bullet Seating

I know they are ... Just want to fix that problem... If they were in Specs.. I'll not writing in here
Any idea WHY they get out of specs After being fired?
Thanks for your input

Are you lubing the inside of the case before sizing it. If not it could be that the expander ball is pulling on the shoulder and stretching it when it pulls back thru the neck of the case.

 

[LCazador]

Factory loads are not intended for reloading purposes. With the WSM cartridges Winchester loads them pretty hot so the brass will be out of spec after shooting. I just went through all this with a friend. Buy Norma brass and be done with it or don't reload just buy factory ammo.

They are lube and I removed the expender ball from the RCBS die

Thanks ... So no way the re used them ? Was trying to save $ ... Here it's about $80-100 a box and they poorly loaded... ES in powder is .8 grain pdwr in Win.
.7 in Brwng and .9 Hrdy
I ALWAYS balanced the powder and set CBTO @ 0.028" from the jam ... This is how I get 1moa @ 200 yrd with Win
And 0.030" with the BXR Brwng

It isn't worth the time or effort. Done, Fini, Hecho, Fertig! Buy new Norma brass.

Get yourself a box of standard brass rounds and try them to see how it goes. What I find strange is a fired factory round will not rechamber in your rifle.

A couple thoughts.
First is that for brass to grow .010” base to shoulder Datumfrom factory new is not uncommon. Most is shipped at minimum or below and will grow to fit the chamber. Nothing to see there.

Setting the die to touch the shell holder and 1/4 turn is no guarantee that they will be touching under pressure at the top of the stroke. Visually confirm there is no gap with a case inserted.

Being able to get .015” feeler gauge between the case head and shell holder is excessive. Measure the distance from the top of the shell holder to the deck where the case sets. Should be no more than .125”

Based on your photo, the shoulder is not contacting the die. Note the bulge at the base of the neck after sizing. Maybe the shell holder, maybe the die. Maybe the base of the case is too expanded to be fixed into the die with the leverage your press has, but it really looks like an issue of the case not getting into the die. With two separate dies, same problem, I’d look elsewhere.

Measure the base on fired and unfired brass and compare diameters report both numbers.

You state that “all is in spec”. This answers has caused more problems with internet diagnostics than any thing else ever. What is the actual measurements, new, fired after sizing. You won’t be the first or last to screw up a spec or math or interpret a drawing wrong.

Note the circled base of he neck. Photos can play tricks, but you should be able to measure that or feel a ridge.

Hope something there helps

Have some Nosler... They are not plated...
Will try them

Neck diam new: 0.338" fired: 0.345" after resised : 0.337
Base of cartridge new: 0.550" fired 0.554"
Resised 0.5515
JUST the shoulder is out of Specs

Well, try the nosler brass. I'm sure someone that you've disagreed with in your comments will be right...

One shell holder is 0.122" the other one is 0.115" I tried them both in both dies

 

[slydo]

Visually Confirm.

Can you chamber a fired round ( before sizing). Also if it were me I would not use nickel plated brass.

100% spot on….. both question and statement
