6.5 x 284 norma help

[pitbull]

I have a 6.5 x 284 norma chambered in criterion barrel. I have redding neck die with bushings and body die. My question is my laupa virgin brass fits perfectly easy to chamber. When I fire them and go to reload them in which this is second firing there hard to chamber takes fair amount of down pressure to chamber them. I have made sure the neck isn't stretched it's like they fire form to the chamber and the body die dosen't do anything. It's not unusable just hard to chamber. Any thoughts ? I have seen a small base body die ?

You need to push the shoulder back a little...

Shoulder bump ^^^^^

Back in the day. I needed to machine a little off the top of my shell holder to push the shoulder back on my fired brass. Just a thought. Use the marker method to figure out where it hits in the chamber and that will help you solve the problem. Safety first. Just use a dummy rou d with no powder or primer.

Full length size, with a bushing for accurate neck tension.

When a case is fired, it expands. Sizing restores the case to its desired dimensions, but you have to carefully adjust your die and press to get this to happen correctly. This adjustment calls for an accurate tool that measures in .001 inches. I like the RCBS Precision mic for measuring base to shoulder height. Unfortunately, RCBS doesn't make one of these for 6.5-284. You might consider using a Lyman case length and headspace gauge to use in conjunction with a digital caliper.

In your third sentence you mention hard chambering. Check with an empty resized case, see if the empty case chambers well. If you were talking a loaded round with a bullet chambering hard it could be a bullet seated to long and the resistance is the bullet touching the rifling. Or it could be the chamber is designed to have the necks turned and an unturned neck is too tight. If you are using a body die it doesn't size the neck could that be the issue? Try sizing with a full length sizing die. It is my understanding that the body die is for moving the shoulder back but does nothing to the neck. Have you checked the cases for length, could they need trimming?

Yes I have a body die and bushing neck die. The loaded round chambers and fires perfectly. It's just after a few firings that it doesn't chamber well. I can't actually remember how many times the spent have been fired 3 maybe. All virgin brass loaded or not chambers perfectly. It was my understanding that the body die does not bump shoulders back. I am going to order a fl die. I wish someone could comfirm. Thank u

Body dies don't bump the shoulders. Buy a FL die, if you want to use bushings, Redding makes a nice FL Type S die that uses bushing.

like effen and ebb said— it many times takes several firings for the new brass to form to the chamber. after that you need to bump shoulder. if you wanna use neck bushings use something like an S die to load so you can push the shoulder back while sizing the case. also check the length of the cases to make sure the neck is not hitting the end of the chamber

Effendude you had me thinking I was losing my mind.

This is wrong? Body dies do set shoulders back. They just do not touch the necks

 

[ebb]

But they have to be adjusted to actually move the shoulder back. You would think that you could adjust till the die touches and go just a little bit more and it would move the shoulder, but for me it's a lot more than that to get results that move the shoulder what you really want. I guess it slop in the press and die, but to get what you want it will take some tinkering.

Might have to take a cut off the top of your shell holder.

If your die wont bump the shoulder back when bottomed against the shell holder
You can do what he said - Grind your shell holder
BUT - I have too many other dies that index off my shell holder
So I don't change the index aspect of my shell holders
since this is not a shellholder problem - but a die too long problem
Hence - I will grind a small amount off the bottom of THE DIE
to correct - THE DIE
you can then bump the shoulder back as much as you wish
------------
You can use a cutoff wheel and grind with the flat side of it for controlled cuts that dont take too much off too quickly - dont use too much pressure with a cutoff wheel, they can crack
it is more like you are polishing with it
I roll the die across a table while holding the grinding wheel to it to get an even cut all around
Quick and easy
If you have a sanding disc you can touch it up to look nice too
But no one is gonna see it anyway

 

[kenacp]

Yes fixing the die is even better.

 

[dellet]

Mark the case so you can see what the actual problem is before grinding dies or shell holders.

Often there is a gap between the shoulder and the neck that is left untouched by both the body die and the neck bushing.

The only way to fully form the shoulder is to reduce the base diameter of the neck.
The only way to fully size the neck is to touch the shoulder.
You can kind of end up with an external doughnut. For all you know it’s a diameter problem at the web. Identify problem before spending money or modifying existing tools.

Grind the bottom of the body die if you grind the shell holder you make it weak and can possibly stick a case, the body die has a large chamfer you can take .040 off and still have a large chamfer and then you can push the shoulders back no problem, you don't have to buy anything just grind or find a lathe and turn .020 off the bottom of the body die
