Fired Brass hard to chamber

thecanadianFired Brass hard to chamber
I just loaded up another 100 rounds of ammo for my daughters 6BRX and found that half of them are hard to chamber, specifically when the bolt cams down. The brass started as 6mm dasher and is now in its 2nd reloading. I first thought that the bases needed to be resized so I ran them through a 308 sizer die but it did not solve the problem. I think its also worth noting that I did not use the crimp on the loading die

Did you neck size or FL size the fired cases? Did you check case length?

thecanadianI did check case length and they are both identical. I am using a 6mm BR die to set the shoulder back followed by a 308 sizer to get the base.

HipshootTake a case that is hard to chamber and pull the bullet and try chambering again, Your OAL cartridge length may be too long !

dpcdAnd if still hard to close, coat it with a black sharpie and it will show where it is touching.

Or simply measure the ones that won't with a caliper and see how much longer they are than the ones that will.

thecanadianI did the sharpie thing and found that the cases were hitting at the neck- shoulder junction. I think I might have figured it out though. I was running out of one-shot and only about half the cases got my normal amount of case lube. When I put them in the sizing die there was notable resistance while sizing ball was removed from the shell. Could this have pulled shoulder back forward? If it did sizing the base would almost certainly pushed it even farther forward.

eagle27To check your theory, remove the sizing ball, size a case then chamber. Yes a poor lubing inside the neck can result in the shoulder being pulled forward enough to give incorrect headspace, I generously brush graphite inside the neck when sizing cases and apply some direct to the sizing ball when starting out to resize a batch of cases.

i'd try reversing this process

thecanadianToday I ran them through the sizer with the decapping pin and they chambered fine, so that must have been the problem. The more I keep fussing with these 2 dies makes me think that investing in the Whidden die is a good idea.

Bill LeeperYou were just using you dies in the wrong order. Sizing the bod with the 308 die first then bumping the shoulder with the 6BR die will do the trick. Regards, Bill.

AtkinsonYou need to full length resize, and your die may be isn't allowing that as it appears you have a 0 tolerance chamber or in other words a bench rest chamber.
You can grind a tad off the bottom of the die, but first I would suggest filing the bullet seat down, so if you over do it a seater is $8.00 and a die is $50. or so.. it shouldn't take much and either way allows the case to go deeper into the die..Do a tad and try until it works, and it will work at some point..

That will only give you a length that WILL and one that WONT !
It tells you nothing !

LamarI'd rather file down the 8 dollar shell holder if I needed the shoulders bumped more.

Then you reseat the bullet in the one that won't to match the length of the one that will duh! If the one that won't is actually longer. And assuming that too long of an OAL is actually the problem.

HipshootThen why bother to measure the one that won't ?

If COAL is the problem it will tell you which will go and which won't. Also safer and easier than trying to chamber each one.
Sorta moot now since it wasn't the source of the OP's problem.

I measure the length of the case from the datum to the case head. Nothing new; L.E. Wilson started selling the Wilson case gage back in the late 30s, my first set of instructions have a printed date that goes back to the early 50s.
Back in the old days reloaders did not get locked up when the case head did not protrude from the top of the case gage.If the case did not protrude from the case gage the case was shorter than a go-gage length chambered from the shoulder to the case head, 'NEXT?' If the case head protruded from the base of the case gage the reloader knew the case was longer than a go-gage length chamber.
The problem? Longer by how much? Wilson suggested using a straight edge, I suggested the reloader use a straight edge with a feeler gage.
No one took me seriously, I have moved on and reloaders are still struggling.
The Wilson case gage was designed to measure fired and sized cases meaning the case diameter when measured in the Wilson case gage could measure a fired case or a sized case. For me it has never been a problem to make a chamber gage from a worn out barrel.
Advantage? It is not likely the reloader is going to be able to stuff a fired case into a go-gage chamber. And if the case protrudes from a go-gage length chamber the reloaders should be able to determine 'by how much'.

If you read my post it is aimed at OVER ALL CARTRIDGE LENGTH----not on any case dimensions !
Two different things !

OK. you are welcome for my effort. I disagree, The OAL is overall length, if your bullet is not seated deep enough it will stay in the barrel when you eject the case. And then there are those that believe seating the bullet into the lands is cool; I don't. I want my bullets to have that running start before the bullets hit the lands. I do not want my bullet to hit the lands and then stop and then decide if it is going to start moving again.
And then there is the Wilson case gage when measuring from the other end; that is the end the reloaders uses to measure case length from the datum to the case mouth or to then end of the bullet for Case overall length.

Do you have trouble understanding things? My post had to do with----AGAIN----OVERALL CARTRIDGE LENGTH !!!

Hipshot, thank you for the kind words. I know how to appreciate a kind word.

I can turn my computer on its side, upside down and or backwards, it does not matter; If the bolt is going to close on my reloaded ammo I know it before I close the bolt, And if the bolt does not close I know by 'how much.
If I need a go gage I make it, if I want a chamber like the chamber in my rifle I will make it. And then there is the darkness, I never cuss the darkness because I have no problem understanding 'things'.
Again, thank you for the kind words.

I know things, If the case is difficult to size when returning to minimum length I have trouble making Imperial look good.
And then there is the shell holder and the .125" deck height.
If the top of the shell holder makes it to the bottom of the die the case is full length sized.
All I have to do to determine if the case has been full length sized is to measure the gap between the bottom of the die and top of the shell holder.

F. GuffeyAnd now we go back to the case gage: The case gage was designed to measure fired cases and sized cases.
Back to "I know things" Wilson suggested the reloader use a straight edge, I do not know of a reloader that has ever used a straight edge. I went one step further, I added a feeler gage.
And then I added dial indicators.
