Resizing with primer in Place

[Envillegc1]

Good evening community

I think I know the answe, but thought I would garner some views!

I have just started to reload my 6.5 Creed, I have previously been loading, 243,223 and 22-250 with no issues.

However, 6.5 is casing me some problems!

Having followed my usual process (maybe flaw no 1, I resized, cleaned, cut to uniform length and then primed.

I made a batch of 15 rounds up for testing 95gr heads, but to my surprise, only 5 would load.

On checking the over 85 I have prepared I have found only 11 more will load.

These are all once fired brass Sellar and Bellet.

So my questions are I guess:

1 Why will some work and others not?
2 Can I try resize with the primer in or do I need to decap the primer? (as they wont chamber I cannot fire them off)
3 Could it be the brass?

Cheers as ever for your thoughts.

Back the decap stem off and resize primed case

Sounds like sizing die not down enough, as said above back decap off and resize.

I agree,be interesting to see what the setting depth and powder charge are,sounds like die isn't properly adjusted and a fairly hefty powder charge to boot

primer not fully seated ?

I think I’d be checking the dimensions of the cases that will chamber & compare with those that won’t chamber. You’ll then know what exactly the issue is & can work out how to deal with it.

Assuming that the cases are from once fired factory ammo that was shot in your rifle, you should be able to simply neck size & reload for at least 4 or 5 reloads. That said I’m not familiar with the quality, or otherwise, of S&B brass.

I've done it with Lee dies, pulled the bullet, with a collet puller so powder still in, resized, reseated.

Obviously the decapping stem wasn't in so didn't turn it into a pressure vessel.

If you resized without the decapping assembly in place your case neck would be much under size and need opening up for correct seating tension?

The bullets seated without needing significantly more force than usual

I’m brand new to reloading but I had the same issue. I use a Lee classic loader that only neck sizes. I remedied the issue by getting a mate with the kit to do a full resize on all my once fired brass.

When I started with my 6.5 cm, I also found that some cases had not sized correctly. I found from measuring that despite going correctly through the sizing die, about 12% of min had “sprung back” (I had attempted to feed them from the top of the magazine into the chamber after trimming and deburring, but before priming).
I then annealed the cases with the issue, using the very basic held in a socket in the flame method. The result after a second run through the sizing die was that all fitted correctly.
S&B cases have quite hard brass it seems.

My next purchase was an annealing machine, currently and Ugly annealer

I hope that helps

Hefty load,what's your h2o capacity and coal, I'll look at grt tomorrow

The weird thing is I did 100 cases in one batch, so the bit I dont understand is why some are OK and others not!

Yes, on the ones I loaded they all seemned the same when seating the bullet heads.

I am full case resize.

that’s a lot of powder… assuming this is what’s in your newly reloaded ammunition? Were the cases you’ve resized from once fired factory ammunition?

Yes.

I've reused s&b brass 5 firings with no issues but that is neck sized.
