Compressed 223 loads cracking neck

Post by TassieTiger » 24 Jan 2019, 8:59 pm

So after sizing my 3rd and 4th fired cases - I examine them for any cracks, etc to ensure that are okay to take to the next step.

However, I've been trialing some compressed 223 loads lately and 1 out of 6 bullet seating's is resulting in very small and minor neck crackings - so i'm left pulling the cartridge and salvaging the projectile and the power and discarding the primed case.
How do you guys know if the neck is fragile - will / might crack - in particular when loading compressed loads that no doubt adds extra pressure to the case ? I'm wasting a lot of primers / time doing it the way I am...

I don't have that problem as I anneal and the cases stay in good condition for the life of them, till the primer pockets start enlarging, sometimes 20 reloads
if I use once fired range brass eg.. winchester I may find some necks with tiny cracks already starting from the crimp that they use that cant be trimmed out so I don't use those cases, I do see the occasional bad case when fireforming cases, I will take the live primers out and use them for fireforming from crap cases

There are better powders pick one of them .......
I only use REM brass and get upwards of 15 loads and have never anealed a case yet but they are mild loads with a 55g pill at 3255fps .

Cracked necks are usually from overworked, work hardened brass. Try not to push the neck around any more than you need to. How much powder are you trying to use? Do you have a long drop tube and tap the case before trying to seat the projectile. Even without annealing you should be able to get ten reloads out of cheap brass.

Yes, maybe, but not always.
I have had circumstances where new unprocessed virgin brass was loaded and cracks appeared on firing. Later inspection of unfired loaded rounds of that same batch were found with neck cracks.
It happens.
Any combination of the following can be the cause.
Poor, incorrect or no anneal from factory
Rough case mouth
Neck too thick
Neck sized too tight
Work hardening
In my experience many instances of poor quality brass seem to emanate from the land of the free. No names no pack-drill.

I’m using Remington brass - some is 3 and 4 shots old(stuff I’ve purchased), some maybe older as it came with rifle.
55gn v max projectiles.
26gn ar2206h
56.7mm oal.
Am gently tapping cases to settle powder but you can still hear a crunch and feel it on the press.
You can actually feel the difference when a neck cracks - lots less seating resistance.
Some cracks are 1-2mm long and some have blown entire necks...

Anneal just the neck and then inside chamfer.
This should mostly resolve the problem.
Anneal by twisting the front half of the neck with the case held in you fingers in a small pinpoint gas flame. When you see a colour change at start of the shoulder that's enough. Either that or your fingers will tell you when it is time to drop the case. Very quick and very easy.
The compressed load has no influence over the cracked necks.
If you don't like the crunching feeling when seating then use funnel with a long drop tube.

sounds to me like very hard brass that needs annealing or throwing and getting some better condition cases :drinks:
you may be able to see the cracks by inspecting the case necks before priming :unknown:

Same here D, I haven't had a need to anal anything and ain't going to anytime in this lifetime :lol:

Seriously though I pretty much run Rem Cases for the most part (cheap enough to buy) and I haven't had any real issues with them either, some of my 22-250 cases would have been reloaded 10+ times now I guess, the 204's have been reloaded 5 or 6 times now I guess and the 223' 3 or 4 times I guess and I think I've had one or 2 necks split over the years, mind you I'm not reloading the case week after week and emptying em at the range, maybe that's why they are having issues (regularly reloaded)? :unknown:

I bought these rem cases approx 4 months ago so reloaded 1 a month...

Annealing is a step I really want to avoid...I think I’ll do as MM advises, buy some new cases and a loupe’.

I have seen some once fired brass that had split which I thought may be a fault in the brass or poor annealing. Most case splitting is cause by overworking the neck during sizing. If you get a once fired case and never size it, just gently dent the edge of the neck so it will hold the pill. A case loaded like this is unlikely to split the neck evenafter many repeated firings.

Heavily compressed loads do put pressure on the neck, some people have been able to crush the neck. 2206 is a nice fine powder for a stick and will settle with a drop tube and tapping.

He is talking about faster powders which use a smaller powder charge.

With the cost of ammo of a 223 and the resultant abundance of one fired cases, I am unsure if it would be an issue to just normal neck size 5 times and then chuck it away.... I reckon you could even FLS 5 times and be fine.

FLS was all I did for many years and probably still do the most (nothing worse than being out hunting and go to chamber a round and find out it don't fit no more cos ya only been neck sizing em. :D
