300 wsm

Outdoor

So Im the new guy here but I have been reloading for 40 years. Never had an issue like this happen before. Also this is my first go around with 300 wsm. I pretty much only shot Sako's and decided to put up the AV deluxe models and hunt with something I don't need to worry about as much. So I just purchased a Grey Wolf 85. I have removed the ejector & firing pin from the bolt so it would be completely free in the action. Federal brass shot once resized and placed into the chamber. Closing the bolt is too tight. I can not get anymore space on the shoulder because of the die ...I am assuming. I have never used Lee dies before ...Is it possible the chamber is so tight and Lee dies are made for the run of the mill chamber That trying to get the shoulder back is not going to happen?
I grew up on Lyman and RCBS dies never an issue. What is everyone thinking? I thought about getting the face milled on the die so the round could move into the die more...maybe 2-3K
If the die physically is not made for what Im trying to do milling may not work. Your thoughts
 
Try measuring your shoulder bump before and after sizing. If you don’t have a tool for this then just use an upside down piece of pistol brass like a 40 s&w.

If it’s not bumping at least .002 that could be a problem. If That’s not a problem then measure the body of the brass before and after sizing at different parts of the brass and see if it’s getting sized back down by .001 or more.

As @Falfan2017 has stated, do some measuring on both unfire & fired brass and also the brass that you've sized in your Lee dies. - That will lead you to find out "what" needs to be done. - I know that if I was in your position I'd be ordering a Redding Body Die if everything was okay except length of shoulder to case head. - It sounds to me like you have a "minimum" chamber or a Lee F/L die that is on the larger side of SAAMI spec's. - If the Lee die will size the body enough and it's just a case-head to shoulder length issue then I'd "mill" an appropriate amount off and go that route if your looking to save $$.

I assume you're over-camming the die as per the instructions ???

If over-camming still doesn't push the shoulder back enough to chamber, you can call Lee and they'll fix the problem.
 
Sorry did n't get back to you guys. Gonna go take some measurements now regarding new, fired and resized
Just curious exactly what would you suggest using to get .002 off of the shell holder?
 
OK tried and take off some meat off of the shell holder.....maybe..??? I got .001 I will call Lee in the morning to get some input from them. Will let you all know
 
Here is the end result. I got on the phone with LEE. They went thru step by step regarding set up. Probably exactly how 99.9% of us would set up.
They recommended sending shot cases, resized cases and a case marked with a sharpie how the shoulder is touching in the chamber. also included the die and they will fix it.
>>>> So just for poops & giggles I reset up the die. Meeting the shell holder and turning quarter turn after backing away the holder. Same results not enough head space
Then I remembered the tech saying a 1/4 to a 1/3 turn after the die touches the holder. Could the 8% (33% - 25% in turn)more of a turn matter, no way I thought. Did the set up again this time I have enough head space!!! We have all set up dies before and tell me honestly who would have thought 1/3 of a turn works and 1/4 turn doesn't? Live and learn . So the Cam over is much tighter, almost to the point of "really"? but I have the results I was looking for, Bolt moves almost completely free, very little if any pressure to close the bolt
I would like to thank everyone for their input.. PS: I did remove about 1/1000 off of the holder
 
Yea I sanded my shell holder as well...before just getting the right dies for my application...( I stopped patching stuff to make it work )
Whidden makes a fabulous die and the click adjustable dies are a really nice added feature.
