Thread: Swapping reloads between rifles

Er don't.

i dont

good advice, I wont.

Looks like a Winchester primer failure to me.

Looks like a loose as goose primer pocket to me

No.These were Murom primed loaded for the AR.

Look closer

Looks very much like a blown primer, as @Gibo said Winchester had a reputation a few years ago for this but it can happen with any primer especially if the pocket is scratched.
Have a look at your bolt face any pitting is a dead give away.

I get that with the Murom primers and federal cases for my bolt .223.
It doesn’t seem to be a gas leak as there are no marks on my boltface but quite a lot of my cases look like that after firing.

In that case the load is to hot AR's are not like bolt bolt guns you can't hot rod them ,
check out some reloading manuals that have load data for the AR platform like Sierra and Hornady

So, information information… It was rounds loaded to your AR and fired through a bolt gun, was reloaded for 1 AR and was fired in another AR or what?
Was it reloaded with the "same powder"??? Forgive me but i have batch of 223 reloaded with BM2 and another with 2208 and they have different powder charge, if you reload with the higher powder charge which the "wrong" powder it could be the cause of "this" thing.
As in one of the previous reply "I" also believe it can be a loose prime pocket or "something else" i cant think about right now. With a good look you actually can see 2 little marks in the case face, one in between "F" and "C" and other above the "22", at least they look "shinier"(if it is a word).
We reloader's pretty much "pray" about "one rifle load may not be suitable for another rifle, use with extreme caution".

Well, i am not an expert in any mains and it is why i am in this forum, to learn. I hope it may bring some light and be of some help. Forgive me if i wrote something that sounds stupid but "I" am human, at least i think i am, and we can make mistakes.

Different brands/types of rifles of the same calibre can & will have different chamber sizes, this is why you don't use reloads made for one in another, if you use a tight chamber reload in a sloppy chamber you will get quite a bit of expansion = blown primers, case head seperartion etc

I dont think thats quite correct. Factory ammo is made to fit easily into the minimum chamber dimension for calibre. Therefore theres lots of expansion going on even in a tight chamber. I see its a federal case, interestingly all the case related reloading problems Ive encountered have been with that brand.

I know nothing about 223 but that primer does not look like its had much pressure. Still very round.

Loose primer pocket, I don't even bother picking up FC brass.

Unless they're quite hot reloads then it shouldn't matter taking them from one rifle to another, otherwise you'd never be able to buy factory ammo.
