Kinda my thoughts as well. Usually the first sign I see that cases are going south are loose primer pockets. I'm having a senior moment here, but the problem you seem to be experiencing sounds familiar with the WSM's. IIRC, it is as cheaptrick is suggesting that there needs to be some fine tuning with the FL resizing die. I'll bet RifleDude know's what's up with that issue.

I have had similar problems in the past with a 6mm Ackley when neck sizing. After running the cases through a full length die, problem solved. Sometimes the expander ball can stretch or pull the case neck when you are resizing causing the shoulder to move forward. This will case hard chambering. Also, try resizing a case and chamber the empty round to see if this same problem occurs.

I am with Roy.  Something during neck sizing caused the case to most likely lengthen.  If the dies are sizing the lower part of the case at all, that also can cause the case to lengthen.  Are you using a special neck sizing die or just backing off with a regular FL die?  If you have a FL die, you do not need to full length resize.  Stoney Point makes a tool similar to the bullet comparator that measures case length from a point on the shoulder.  Measure a fired case that chambers ok prior to sizing.  This will give you a reference for your chamber.  Then resize the brass and measure again.  Screw in the die slightly and repeat.  Continue this process until you set the shoulder of the brass back 2 thousandths from your reference number.  This should ensure reliable feeding in your chamber and not excessively work your brass, thereby lengthening it's life.

jbird,

I don't own a .300WSM, but I do own a 7WSM and I haven't had this problem.  In order to narrow down the source of the problem, can you provide the following information? 

 

1.  Are you trimming case OAL back to 2.100" or less?

2.  What is the neck wall thickness of your cases?  Early WSM brass was reportedly very thick, while current brass has thinner wall thickness.  Proper wall thickness at the neck should be around 0.015" or so.  There seems to be a wide variation in WSM brass thickness. 

3.  If you're neck sizing only, you may not be setting the shoulder back to proper headspace to allow bolt closure.  Are you setting up your sizing die so that you get the proper shoulder bump back to 1.802" (at the neck) / 1.664" (at the body)? 

 

As was mentioned, if you aren't full length sizing already, doing so may fix the problem.  The .300WSM is a very high pressure cartridge and it only has about 0.017" of body taper, which can make fireformed brass difficult to chamber.

 

Please keep us posted on what you discover.

jbird,    sounds like a 10FP..??  Been shooting Savage for many years..Have seen many "bugs" from them ..Usually clearence or tolorance issues..The last tactical unit i purchased (.308) has an extremely tight chamber...  Shows carbon leaking arround the neck( no clearence to expand and seal correctly)  TIGHT..!!!!!!!  Chambering was difficult from the beginning...  If you use LEE full length sizer try this,   when you set the die up in the press, the usuall technique doesnt work....Extend the press ram and adjust the sizer die to TOUCH the shell holder and ADD another 1/4 turn....Lee dies wont bump the shoulder unless you do this...You should always lube brass, especially the neck and when you shoot the Savage bump the shoulder, they are always TIGHT....

 

Hope this helps, 30

Hey bird, just curious; did you ever find the solution to this problem?  We have a few WSM shooters here that would be interested in your findings.

Yes, I shoot 7WSM.  Winchester is the only brass I've used so far, and I believe it's the only brass available for the 7WSM at present, but I've heard rumors that maybe Lapua may produce brass for it.  If you want an alternative to Winchester brass, one thing you can do is get some Norma .300WSM brass and run it through a 7WSM sizing die.  The headspace on the 7WSM brass is some 0.040" longer than the .300WSM brass (and .270WSM as well), but by running the .300WSM brass through the 7WSM sizer, you create a false shoulder on the neck for fireforming that makes this a safe practice.  DO NOT go the other way and try to fireform 7WSM brass from .270WSM due to the excessive headspace, which can cause case head separation.

I guess after the fire forming you have brass that is good to go... What does this false shoulder look like before you blow it out..??  Do you have a load you prefer to use for the forming..??   You like NORMA brass.??

 

                      Thanx

Pyro, The weather getting any better..??  This is off topic, but I tried something the other day...  I ripped the scope of my sons rifle ( simmons whitetail classic) to see how my eyes liked their PLEX retical...  I jammed the power on 20x and went to work..Ya know this thing isnt bad for what it is..  Im playing with a fixed power idea so I wanted to see whats up..At 50 yards and 20x power that plex is pretty quick.!! Moving to 100 yds is just as quick..Quick for my eye takes some doin these days...

30,

Due to the 0.040" difference in shoulder height between .300WSM and 7WSM, when you run the 300 case in the 7 FL sizing die, the neck portion of the sizer doesn't reach all the way to the shoulder and bump the shoulder like it would with the 7 case.  Therefore, it leaves a larger, unsized ring at the base of the neck -- the "false shoulder" -- that the case headspaces against while fireforming.  Fireform with a mild load, trim to length and yes, you're good to go from there. 

 

Norma brass overall is pretty good, though I haven't used much of it.

Rifledude,  When your done fireforming we have moved the shoulder .040 forward...Do you think there is a thinning of the brass where the previous shoulder intersection was.??  (at the body)
