257 Wea Problem

[338Lapua]

No everything needs to be precision to function properly, after reading through the responses I went and measured 5 of my shell holders i have on hand, and i though it was a good cross section.
1 RCBS 1 Pacific both I bought back in 1980….. 3 Redding, one of which comes from a competition set that I bought two years ago.

All but one measured exactly the same, 0.250 only one of my Redding shell holder measured 0.253 0.003 difference. i wouldn’t think enough to make a difference in a factory chamber.

I have herd people talk about shell holders being different thickness before and they machining or filing down. But i have never struck it in all the years of reloading… I”m not saying it’s not true it’s that I have never in counted it.

 

[RJ338]

It is not the overall thickness of the shellholder, but of the depth ftom the top to where the case sits (approx..125)

 

[338Lapua]

Thanks RJ338 I measured them again and there are differences with the Redding comp shell holder, its 0.011 thicker compared the others, which are with in 0.001 of each other still barely enough to make a difference in a factory chamber

 

[338Lapua]

One thing I hate is people that make snide smart comments for not good reason really help full…. all that’s does is get me pissed, I shall leave it right there.

I refuse to put up with a clown like you in a forum that means nothing to me or anyone else in the real world. Sorry for not paying umbrage to the for most expert.....I forgot how well known you are in the shooting world.. judging by your posts you have nothing else better to do with your time....I do, and I'm not wasting a second more on you.

I apologize to all for getting the subject side tracked, especially the OP and 338Lapua, I have removed my last two posts, I would like to see this thorough and get jsthntn247 problem solved for him one way or the other, when finished we will all have learned something.

Wow, this thing got side tracked fast. Getting back on the subject, I have measured this brass every way possible. Everything before and after sizing is still within saami specs. I thought it might be case head expansion, it's not, I thought it might be the bulge above the belt, its not. I thought it might be bumping the shoulder, aint that either. The only other thing that it can possible be is burrs in my chamber or what I think is really the problem is the bolt head. Remlins quality control lately has sucked a major fat one here lately and I think this might be my issue. If I could find someone with the same boltface and long action, that isn't having any problems, I could try their bolt in my rifle and see if it's still tight, Right????? If so, what other callibers are compatible with a .257 boltface?? All my other guns are Savage's for this exact reason.

Please don't get hung up on SAAMI specs. Your rifle may be out of spec, but the factory ammo fits fine, as does your fired brass. Your sizing/loading practices are changing something.

jsthntn247,
Send me a piece of once fired brass, untouched from your chamber that Will still chamber in it , also send me a couple or three pieces that won't chamber in your rifle that you have resized, I will see if it will chamber in my .257 Wby I can also take it to work if necessary and run them in our comparator, if there is any dimension differences it will find it, if interested p.m me your mailing address and I will p.m you my mailing address and we will try to get this rung out for you.

That right there is a deal I can't refuse.

I find Wilson case gauges less useful than a caliper attachment for determining relative "headspace" of loaded ammo, fired, and sized cases. If I may be so bold, I would suggest that one of the Hornady gauges might help illuminate your situation. In the past, i have found that unfired .300 Weatherby brass was .021 shorter at the shoulder than a case that was once fired in a factory chamber. One thing that I would trust the Wilson gauge for is case length sorting. If any of your cases stick up beyond the gauge, I think that your should trim them till they don't.

 

[jsthntn247]

I just tried to resize some of my once fired cases to send to . Now that I am looking extremely close, I can see that it is bumping the shoulder's back waaaay too far. I had to back my die off .436 from touching the shellholder until it would chamber easy and still size the neck. RCBS suggested that I send the fired brass in with the die to let them look at it. I am to the point where it seems easier to just neck size the brass till it won't fit and then throw it away. If I fl size like this, I am only sizing 3/4 of the case??

That is what I suspected from the beginning, I am very glad you have figured it out as hunting season is here. Now I would suggest you send the die back for possible free replacement and in the mean time buy a Redding body die and use it in conjunction with your neck die and your problems will be a thing of the past. You really need to do as Boyd said and buy yourself a set of Hornady or Sinclair bump gauge set for you vernier calipers and you could have saved yourself a huge headache, best of luck to you my friend

JS
Try taking a piece of fired, resized brass and ink it with marker, than chamber it and see where the rub is.

When resizing check and see if the neck and shoulder are getting pushed to far and budging the case, where the shoulder and the body meet.

Actually Hal hit it on the head after re reading it all. Doesn't matter you got it now

I'm glad you got the trouble cured.

You might try to find what is causing the scratches on your cases and polish that out.
