M1A reloading question?

Guy's, I spent the day resizing and getting to reload my one batch of nny mil-surp brass... This will be it's 5th reload by me...

Question?: When is 'end of life?'... Case heads are getting so 'dinged up' they do not enter my shell holder with ease but the primer pockets are still tight.
I have one 10 round set that has seen 11 reloads by me and are used for 'fouler' shots...
Am thinking 8 reloads and then reload up with 'plinker' ammo to not pick up?
??? is there an accuracy difference?
Jeff

Jeff,
4 is about my limit. You've probably read the posts about stretched out matching gun brass that's sold as surplus. I stay away from it. I buy new boxer military surplus ammo and reload that brass as I know it's history. I'm guessing the bench shooters will have some input work hardening, neck tension and accuracy.

Thanks from JEFFJP_N_JJ

The violent extraction cycle of the M14 pulls the case apart near the web. In bolt guns this is called incipient case head separation (ICHS).

To detect ICHS, we use the bent paper clip trick. Take a paperclip, and using needle nose pliers take the last 2mm of the paperclip and bent it 90. Now you can stick the bent tip into the fired case and feel the inside of the case wall down near the web. If you feel a noticeable dent, the case should be considered toast--the case wall is thin enough to rupture on the next firing.

Thanks Douglas Haig,

Yes, I have seen and read all those posts and have had ONE LC brass I tossed out after a 'ring' and not passing the paper clip test... I agree Douglas I will not buy any more 'once fired' brass... I will reload and shoot the brass that was fired out on my rifle or one similar that I know about as is my nny brass...
The 'beat up' case heads concerns me with the nny brass for accuracy?

I'll push my cases up to 5 reloads if they still look pretty good. Try standing two cases upright (head down) on a flat surface next to each other. Then rotate one case until you find the maximum gap between the necks. Then rotate the other case likewise. Then rotate the cases to find the minimum gap.

What this shows is how the cases have stretched more on one side than on the other, adopting a 'banana' shape. It can become surprisingly large after several reloads. I figure that shape has to cost me some accuracy, but mostly I'm concerned with weakness in the stretched side of the case.

Yes the case rim gets chewed-up. I basically use the shell holder to reshape the rim - when it's too bad the case gets tossed.

The number of reloads depends on the pressure of the load, and how much shoulder setback is done when resizing. With mild loads and 'just enough' setback, you get longer case life.

The 'common wisdom' for safety is to stop at about 5 firings.

I hate getting a rim hung up on the shell holder. I always toss those when I get it free from the shellholder.

My inspections are with a flashlight after three and four firings. If I see a light ring on the inside (usually after 4 firings) I paper clip it. Most of the time they pass. I load em one more time.
If I see a dark ring (that usually goes 3/4 to all the way around) I paper clip test it and it usually fails. I toss em.
Similarly to the above posts, the case rims that are beaten up is a sign of at least three loadings/4 firings.
I try to fire/reload all my brass completely so that all pieces are on the same cycle/number of loadings.
I load about half a grain/full grain off max all the time. Shoulder bump is 2 thousandths off max.

Good luck.

I toss after 5 firings almost every time. For safety and piece of mind/liability too. Others shoot my rifle and I don't want...well you can imagine.
I have loaded CBC brass the most of all the brass I have fired. 8 times without a sign of a ring.
Remington the least. Ring starts to show up after two firings.
LC brass is the avg. 4-6 times before a ring.
Obviously the hotter the load the faster the ring shows up.

For me depending on brass on the 4th load I'll load them and throw them in an ammo can for a rainy day...

dantheman114,
Yes, thanks, my thoughts as well... Just wondering how many loadings to make the switch...
Have one thrower set to 43.0 grains of WW748 and bought some 150 grain Hornady fmj I intend to check this weekend as my 'ammo box' load.

Do you have access to a metal detector? I have to deal with a good bit of snow at times and hate to loose any of a "set" of like brass with equal numbers of reloads on them.

You may try laying a plastic tarp over the snow to catch the brass if you are shooting in one place and can predict the "catch" area.

Thanks from ConRich

I found that an old bedsheet or blanket worked better than a plastic tarp which melted on the hot brass and is a PITA to clean off.

Good point. Although I haven't had any brass melt a plastic tarp yet, it could happen. I have used canvas tarps, blankets, and bedsheets as well. Very easy to police the brass - if a sudden gust of wind doesn't interfere. Just pull up the four corners and you're done. :-)
